EJPut Posted July 10, 2004 Report Share Posted July 10, 2004 Can I relieve the fuel pressure in the system without using the guage with bleeder hose as it says in the manual? I am changing the filter and I would just like to push in the valve to relieve the pressure and then change the filter. Thanks, Eric Link to comment Share on other sites More sharing options...
bigfoo Posted July 10, 2004 Report Share Posted July 10, 2004 You can do whatever you want, if you want to get sprayed with fuel go ahead :> I think it will depressurize after some time if you let it sit, but sometimes we don't have that luxury Check what the FSM recommends on how to change the fuel filter. If you don't have one I Can check mine and see what it says, although it's for a 99. Link to comment Share on other sites More sharing options...
98Concours Posted July 10, 2004 Report Share Posted July 10, 2004 Just put a towel over the Schrader (sp) valve on the fuel rail and press the little thingy and the fuel will spray out into the towel.

EJPut Posted July 10, 2004 Author Report Share Posted July 10, 2004 Sounds good to me, I kinda thought that I might be able to do something like that but wanted to be sure....gas = boom! Link to comment Share on other sites More sharing options...
Ranger Posted July 10, 2004 Report Share Posted July 10, 2004 You can also pull the fuel pump fuse or relay. Then start the car. It won't run long, if at all but the fuel system will be depressurized. Link to comment Share on other sites More sharing options...
jgr7 Posted July 11, 2004 Report Share Posted July 11, 2004 I just let mine sit for 10 min and wrapped a towel around it , have a small bowl also for fuel to drip into, very easy job 10 min. Jeff Link to comment Share on other sites More sharing options...

Forget the fuel pump fuse....The fuel pump has a secondary electrical feed from the oil pressure sender circuit. As long as the engine cranks long enough to build adequate oil pressure, the fuel pump will be energized and the engine will start and run.

KHE Posted July 11, 2004 Report Share Posted July 11, 2004 I got my card punched a couple of years back with my old Park Avenue..... I was replacing the fuel lines from the sending unit to the engine and I pulled the fuel pump fuse per the directions in the shop manual I might add.... I started the car and waited for it to run out of gas....after 5 minutes, the engine was still running.....WTF??? I looked at the wiring diagram and discovered the auxiliary feed through the oil pressure sender.....
