I remove the fuel pump fuse or relay while the engine is running. The engine will run until the pressure has dropped. Leave the fuse or relay out until you have finished replacing the fuel filter.
No, you do not have to and in some cases you cannot. Unless your car has a fuel rail pressure relief valve, you can only be prepared for the spray of fuel when you disconnect the filter.
it isn't necessary to relieve any pressure prior to replacing the fuel filter on the 2005 Impala, however be mindfull of the gas tha is in the lines and in the filter when it comes off
Right next to the oil filter, it kinda gets in your way when you are replacing the filter.
Should be the same as my 1989 323; 40 PSIG (280 kPag). Please note this is on the discharge side of the high pressure pump, before the fuel filter. Good luck Malcolm
Release the fuel pressure by opening the gas cap first, than pull the fuse for the fuel pump. Start the car, it will sputter and die from lack of fuel pressure...now safe to change out the fuel filter. I'm not a safety freak...but let me advise wearing safety googles.
The filter is one specially made and designed for this vehicle. You will have to have it ordered in before replacing.
Usually the pressure gauge on your pool equipment indicates how much pressure there is before the filter. as the pressure goes up it indicates that the filter is getting blocked and needs a backwash or cleaning. while the pressure is low the filter does not need cleaning.
Most have a bag and a filter. Try replacing the bag and the filter. If it has a revolving brush, remove the brush and wash it, let it dry before replacing it.
remove gas cap Removing the gas cap will not relieve any pressure between the fuel pump and the engine.
Try replacing the pollen filter, that will cure the problem.
try replacing the delta pressure feedback sensor. this fixed my explorer.Or you can try replacing the relay.
If the vehicle is not running, then the fuel line is not under pressure and replacing the filter is very easy.There will be some fuel spillage from the old filter, so be prepared to catch it and wear eye protection just for good measure.
