2001 C240 - Guide for Fuel Filter Change D.I.Y.

[djnevoc]

You can get a Fuel filter for your c240 at any Autozone / Advance Auto <-- (10% Military Discount).

This guide should work for any C240 between 99-2005.

Tools Needed:



1 Torx Socket
1/4" Socket
10mm Socket
Box that the filter comes in.
Drip Pan
Safety Glasses
Wire Cutter Plyers
Paper & Pen - I like to make diagrams, so when people call me I don't forget how it goes together.


Parts Needed:
4 - #4 Hose Clamps
1 - Fuel Filter

Notes Before starting:

If you have a lift you can use this project will be MUCH easier. Other wise use a jack. (Block your tires)

I used a lift, When you go to remove the skid cover You cant take it off because the cover is part of the lift point.

Location of the Fuel Filter:

Just in front of the Drivers side Rear axle.

Remove your gas cap. The fuel system is a pressurized system so by removing the cap you wont have alot of fuel running everywhere.

Lift the Vehicle.

Use your 10mm socket and remove the 4 Plastic Nuts holding the left skid cover in place.

I placed my cardbox box the filter came in between the cover and the underside of the car to hold the cover down.

Use your Torx wrench and remove the single screw.

Unclamp the two upper hoses that attach to the out plastic filter holder and then lift up and it comes free.

Take wire cutter plyers and cut the left side hose clamps off. (I twisted them free and bent them back off.)

Your hoses may twist off, but mine wouldn't, SO place a flat tip screw driver between the base of the hose and the filter and pry it up till it comes free.

Once the two on the left are removed, use the same technique on the right side.

Now reinstall the hoses in reverse order.

Now apply your 4 hose clamps

Tighten with the 1/4" socket.

Reinstall the plastic filter holder and Torx Screw & Clip hoses into plastic filter holder.

Wipe up all te spilled fuel from the cover.

Reinstall the 4 Plastic 10mm Nuts for skid cover.

Remove Lift/Jacks

Reinstall Gas Cap

Start the car. (NOTE: Now that there is air in the fuel line it may take a second or two longer to start the first time. My car normally is started within a second, it took nearly 3-4 seconds to start, and considerably noticable difference. Turn off the car and start again, car should start normall)

I hope this Guide Helps!!

you need to add a pair of gloves to your parts needed, its looks like you just had a cut while doing it. J/K

otherwise it a very good illustration and instructions, good job. THANKS.

[djnevoc]

I didn't wear gloves because if you get them soaked in flammable fluid it doesnt come out, and that is a major safety hazard for my line of work...(Helo Pilot).

But yeah those hoses on my car were actually very difficult to get off on my car and I slipped my screw driver... no biggie.

Great info man! That salt coating (yuck) on the car reminds me why I live in south FL!

with air in the system. once you start it will this affect the fuel system? or will the air naturally escape once you start the car?

thanks

Good Question, Like I mentioned the car will take a bit longer to start. This is because the system needs to re-pressurize, so the basically the air will be forced through the system and will once your car starts all the air should be out of the system.
