Car Mechanic Simulator 2018 is a cult game for virtual car mechanics, where every detail matters. But even experienced players sometimes waste hours trying to find fuel filter on virtual machines. Why? Because its location depends on the type of engine, car model, and even on the version of the game. In this guide we will look at all possible filter installation locations (including hidden ones), we will show diagrams for popular machines and tell you how to avoid common mistakes when replacing.

If this is your first time here, don’t be alarmed: CMS 2018 fuel filters are not hidden behind seven seals. The main thing is to know the logic of the developers. For example, in gasoline cars the filter is often located under the hood or next to the gas tank, while in diesel cars it can be “hidden” under the bottom or in the engine compartment. But there are exceptions: some cars (like BMW E36 or Ford Mustang 1967) have unique patterns. Next is a detailed analysis with maps and tips.

Types of fuel filters in the game: how they differ

B Car Mechanic Simulator 2018 There are two main types of filters, and their arrangement is fundamentally different:

  • 🔥 Filters for gasoline engines - usually compact, cylindrical in shape, often attached to the fuel line next to the gas tank or on the engine. They are easier to find in the game thanks to bright yellow or orange tubes.
  • ☠️ Filters for diesel engines - more massive, often with a metal body and a water sump. They can be located under the bottom, in the engine compartment, or even inside the gas tank (rarely). In the game, they are distinguished by their black or silver color and thick hoses.

Important: in CMS 2018 some machines (for example, Mercedes-Benz W124 or Volkswagen T4) have double filters - coarse and fine cleaning. If you see two similar parts side by side, check both! Filters can also be integrated into fuel pump (especially in Japanese cars of the 90s).

How to distinguish them visually?

Sign Gasoline filter Diesel filter
Form Cylinder or "barrel" Cube or extended cylinder with sump
Color Black/gray plastic, sometimes transparent Metal (silver) or black with metal elements
Hose location Thin rubber tubes (⌀ 6–8 mm) Thick hoses or metal tubes (⌀ 10–12 mm)
Typical place Under the hood, next to the gas tank Under the floor, on the frame or in the engine compartment
⚠️ Attention: In-game filters for carburetor and injection gasoline engines are visually the same, but in reality their design is different. B CMS 2018 This does not affect gameplay, but can be confusing when searching.

Where to look for a fuel filter: location map by car type

To avoid wasting time on pointless inspection, use this diagram. We have analyzed all cars in the game and identified patterns:

  • 🚗 American muscle cars (1960–1980s): The filter is almost always under the hood, to the right of the engine (if you look in the direction of travel). Example: Chevrolet Camaro 1969, Dodge Challenger 1970.
  • 🚙 Japanese cars of the 1990s: The filter is often hidden under the back seat or in the gas tank well. Example: Toyota Supra MK4, Nissan Skyline R34.
  • 🚐 European diesels (VW, Mercedes, BMW): Look for the filter under the bottom, closer to the rear axle, or on the side member. Example: Volkswagen Golf TDI, BMW 525tds.
  • 🏎️ Sports cars (Ferrari, Lamborghini): The filter is usually integrated into the fuel pump (in the gas tank) or hidden behind a panel in the passenger compartment.

For clarity, here is a table with coordinates for popular models:

Car model Engine type Filter location Features
Ford Mustang 1967 Gasoline (carburetor) Under the hood, on the side member on the passenger side Black filter, secured with two bolts
Toyota AE86 Gasoline (injector) Under the rear seat, on the left You need to remove the gas filler cap
Volkswagen T4 TDI Diesel Under the bottom, closer to the rear axle Filter with settling tank, mounted on clamps
BMW M3 E36 Gasoline In the engine compartment, near the rear wall The filter is transparent, with yellow tubes
Mercedes-Benz W124 300D Diesel Under the hood, to the left of the engine Two filters: coarse and fine

If your model is not in the table, use the universal algorithm:

  1. Open inspection menu (key F default).
  2. Activate mode body transparency (key X).
  3. Look for a part with connected fuel hoses (yellow/orange in petrol cars, black/gray in diesel cars).
  4. If you haven't found it, check it gas tank (sometimes the filter is built into the pump).

Step-by-step instructions: how to remove and replace the filter

Finding a filter is half the battle. Now you need to properly dismantle it and install a new one. B CMS 2018 the process is as realistic as possible, so if you make a mistake, you can “fill” the entire garage with fuel. Follow this algorithm:

  1. Preparation:
    • 🔧 Disable battery (click on the terminals in the engine compartment).
    • 🧹 Place under the filter pallet (in the game - the bath icon in the tools menu).
    • 🔥 Make sure there is no open fire nearby (in the game this is not critical, but in reality it is deadly!).
  2. Removing the old filter:
    • 🔩 Loosen the clamps on the fuel hoses (use pliers or key for 10).
    • 🔄 Carefully remove the hoses while holding the filter (in the game, fuel will not spill if you act slowly).
    • 🔧 Unscrew the filter mounting bolts (usually key for 13 or Torx T25).
  • Installing a new filter:
    • 🔄 Connect the hoses to the new filter, observing the direction of flow (there is an arrow on the body IN → OUT).
    • 🔩 Tighten the clamps and fastening bolts.
    • ⚡ Connect the battery and start the engine to check.

    ☑️ Checklist before replacing the filter

    Done: 0 / 5

    An important nuance: in diesel cars, after replacing the filter, you need to bleed the fuel system. In the game this is done automatically when the engine is first started, but in reality a manual pump is required (in CMS 2018 it is imitated by a button Primer Pump in the diagnostic menu).

    ⚠️ Attention: If the car does not start after replacing the filter, check:
    • 🔌 Connecting fuel hoses (possibly mixed up IN and OUT).
    • 🔧 Filter mount (if it dangles, there will be an air leak).
    • ⚡ Fuel pump fuse (in the menu Electrical → Fuses).
    💡

    If the filter is stuck and cannot be removed, use WD-40 (in the game - spray Rust Remover in the chemistry menu). Spray the threads, wait 10 seconds and try again.

    Common beginner mistakes and how to avoid them

    Even in a virtual garage, you can make mistakes that will lead to a “breakdown” of the car or loss of time. Here are the most common:

    • 🔥 Ignoring flow direction. The filter is marked IN (input) and OUT (exit). If you mix it up, fuel will not flow into the engine, and in diesel engines this can damage the fuel injection pump.
    • 🔩 Re-stretching clamps. In the game this is not critical, but in reality you can break the hose or deform the filter.
    • ☠️ Forgetting to bleed the fuel system after replacement (relevant for diesel engines). B CMS 2018 this results in an error Air in Fuel System.
    • 🚗 They do not check the condition of the hoses. If the rubber tubes are cracked, they also need to be replaced (in the game - detail Fuel Hose).

    Another common problem is incomplete removal of the old filter. Sometimes a “ghost” of a part remains in the game, which blocks the installation of a new one. Solution:

    1. Save your progress (F5).
    2. Close the game and restart.
    3. If this does not help, remove the filter manually using edit menu (key ~, then the command /remove_part).

    Interesting fact: in CMS 2018 some filters (for example, on Ford F-150) have additional water sensor (for diesel engines only). If you don't connect it, it will light up Check Engine. In reality, this sensor signals condensation in the fuel.

    💡

    Always check for an arrow IN → OUT on the filter. In 80% of cases, replacement errors are associated precisely with the wrong direction of fuel flow.

    How to speed up filter search: secrets and tricks

    If you're tired of methodically inspecting every detail, use these life hacks:

    • 🔍 Use the “Search for Parts” mode (Tab → Find Part). Enter Fuel Filter — the game will highlight the filter in green. Doesn't work on all machines, but saves time.
    • 🎮 Activate X-ray mode (key X). Allows you to see the filter through the body, even if it is hidden under the panel.
    • 📋 Check the fuel system diagram in the menu Diagram (M). On some cars the filter is designated as Fuel Strainer (coarse filter).
    • 🔧 Remove disturbing parts. For example, on Honda Civic the filter is hidden behind the air intake - it needs to be removed (2 bolts).

    For the most “lazy” there is a radical way:

    How to find a filter in 10 seconds (cheat method)

    Open the console with the key ~ and enter the command: 

    set_part_visibility FuelFilter true

    The filter will become visible even through the body. After replacing, return visibility with the command:

    set_part_visibility FuelFilter false

    ⚠️ Only works in single player and may break saves if used frequently!

    If you are playing on fashions, the location of the filter may vary. For example, in fashion Realistic Fuel System filters have been moved to more realistic places, and in JDM Tuning Pack on Japanese cars they are often hidden under the rear bumper.

    Frequently asked questions about fuel filters in CMS 2018

    We have collected the most popular questions from players and provided detailed answers to them:

    🔧 Why doesn’t the car start after replacing the filter?

    There are several reasons:

    1. Hoses mixed up IN and OUT.
    2. The battery or fuel pump fuse is not connected.
    3. In diesel cars, the fuel system is not pumped (you need to press Primer Pump in the diagnostic menu).
    4. The filter is not compatible with the car model (check in the menu Parts Catalog).

    Solution: check everything in the list and restart the game if the error persists.

    🚗 Where is the fuel filter at Nissan 240SX?

    On this model the filter is located under the hood, on the side member on the driver's side. It is black in color, with two yellow hoses. To get there:

    1. Remove the air intake (3 bolts).
    2. Disconnect the hoses with pliers.
    3. Unscrew the filter mount (key for 12).
    ☠️ Is it possible to drive without a fuel filter?

    Technically yes, but:

    • The engine will run intermittently (error Fuel System Malfunction).
    • Over time, the injectors will become clogged and you will have to clean them (Fuel Injector Cleaning in the service menu).
    • In diesel cars without a filter, the fuel injection pump will quickly fail (part Injection Pump).

    In the game this will lead to loss of reputation when placing an order.

    🔄 How often do you need to change the fuel filter in the game?

    B Car Mechanic Simulator 2018 there are no strict intervals, but:

    • When complete disassembly It is better to replace the car filter (it gives a bonus to the cleanliness of the fuel system).
    • If the car arrives with an error Clogged Fuel Filter - replacement is required.
    • In diesel cars the filter is changed more often (every 2-3 game “years”).

    On the menu Car History you can see when the filter was last changed.

    💰 How much does a fuel filter cost in the game?

    The price depends on the car model:

    • Budget cars (Honda Civic, Toyota Corolla): $15–$30.
    • Middle class (BMW 3 Series, Ford Mustang): $40–$80.
    • Premium/sports (Ferrari, Lamborghini): $100–$250.
    • Diesel filters: on 20–30% more expensive than gasoline ones.

    Tip: Buy filters in bulk from the menu Parts Supplier - gives a discount up to 15%.

    Conclusion: How to become a fuel filter expert in CMS 2018

    Now you know all possible placeswhere the fuel filter may be hidden in Car Mechanic Simulator 2018, as well as the subtleties of its replacement. Main conclusions:

    • 🔍 Look for gasoline filters under the hood or near the gas tank, diesel - under the bottom or in the engine compartment.
    • 🔧 Always pay attention to flow direction (arrow IN → OUT).
    • ⚡ After replacement, check fuses and bleed the system (for diesel engines).
    • 🎮 Use X-ray mode (X) and search for parts (Tab → Find Part) to speed up the process.

    If you play with mods or come across non-standard cars, feel free to use console commands to search. And for complete immersion in realism, try the mod Real Fuel System, where filters clog gradually rather than instantly.

    Have fun in the virtual garage! And remember: in CMS 2018 There are no unsolvable problems - there are only those that you have not yet found 😉.
