I saw a thread about an RS....is there a fuse I have to take out? Wagon Joe 07-09-2004, 11:42 AM there is a writeup on scoobymods.com the fuel filter is in the rear-driver's side of the engine bay. It has two protruding nozzles that attach to the fuel lines. Wagon Joe 07-09-2004, 11:44 AM here is the link ;) Fuel Filter Replacement instructions (http://www.scoobymods.com/forums/showthread.php?t=3645&highlight=fuel+filter) Mulder 07-09-2004, 11:49 AM It's the round can with two hoses attached, by the driver side strut tower. There is a clamp that holds the filter to the bracket, once released it can be disconnected and removed. Before disconnecting the hoses, you need to depressurize the fuel system. By the passenger side kick panel, under the glovebox, you will see a green relay with a green plug. That is the fuel pump relay. Disconnect it, and then crank the engine so it starts and dies. Repeat this a few times until it just cranks. Then, remove the gas cap. These steps should relieve most of the pressure in the system. You can now disconnect the hoses from the old filter and attach them to the new one. Keep some rags handy as there will still be some fuel coming out when you take the hoses off, be prepared for it. Have the new filter right there so you can do the swap as quickly as possible and minimize any fuel leakage. It's safest to do this when the engine is cold, so any spillage won't be going onto a hot surface to possibly ignite. After the new filter is in place and the clamps tightened, close the gas cap and reconnect the fuel pump relay. Before cranking the engine, turn the key to "run" for a few seconds to allow the pump to run and prime the system, then back to off. Do this a few times to build some pressure before actually cranking to start. It may still take a bit longer than usual to fire up, once it does check the filter for any leaks. In the event you get a CEL after the swap don't worry, it's just from extended cranking with the pump relay unplugged. It will go out after you drive the car for a while. vtownrida 07-09-2004, 01:41 PM wow thanks mulder......that explanation was perfect Psydotek 07-09-2004, 02:26 PM It's the small black or silver "canister" that's sitting on top of the indentation of the windshield wiper fluid reservoir. :) Do it while the car is cold, i.e. first thing in the morning or something. If you have 2 forceps or binder clamps you can put those on the hoses so you don't get fuel spraying out either. In additon to making sure the in/out hoses are attached to the proper tube, make sure not to drop any of the items that hold the filter in place deep into the engine bay... :D [one of if not the easiest maintenance items really] grindMARC 07-12-2004, 05:13 PM How many people read the thread about the guy that watched his car catch fire and burn after taking it for a test drive immediately after the fuel filter swap? BE VERY CAREFUL not to start the car for a while if you spill ANY fuel. avk 07-12-2004, 06:07 PM A good safety measure is to spread some rags under and around the filter, and to plug the hoses as soon as they are disconnected. Good plugs can be cut out of wood (chopsticks work well), or one can use 8mm screws. Opening the tank won't relieve the pressure because there's a check valve in the line after the pump.
