brake Posted November 22, 2011 Report Share Posted November 22, 2011 Never done one on a W body, just on b.o.f cars where it is along the frame rail. Is it near the tank on these cars? Is there by any chance a fuel pump inertia switch somewhere so I can kill the pump to relieve pressure? Conversely, what's the preferred method of relieving fuel pressure on these rigs?

94 olds vert Posted November 22, 2011 Report Share Posted November 22, 2011 I've never relieved the pressure on these cars to change the fuel filter. It's really easy to change on these cars. It's in front of the tank facing the front of the car. Quote Link to comment Share on other sites More sharing options...
brake Posted November 22, 2011 Author Report Share Posted November 22, 2011 Cool, thanks. Anything I've done a filter on without relieving pressure has given me a nice fuel bath for my hands I'll give it a go without anyway. Quote Link to comment Share on other sites More sharing options...
94 olds vert Posted November 22, 2011 Report Share Posted November 22, 2011 You'll get some fuel to spray out, but it's not that bad. Quote Link to comment Share on other sites More sharing options...

slick Posted November 23, 2011 Report Share Posted November 23, 2011 Pull fuel pump relay or fuse and start the car a few times, should help relieve most pressure. Quote Link to comment Share on other sites More sharing options...
White93z34 Posted November 23, 2011 Report Share Posted November 23, 2011 [ATTACH=CONFIG]6839[/ATTACH] :lol: You can also relieve pressure by pushing the schrader at the fuel rail make sure you put a rag over it. Quote Link to comment Share on other sites More sharing options...
Leo090 Posted November 25, 2011 Report Share Posted November 25, 2011 On my Chevy Lumina there is a fuel line extending from the fuel tank to my engine. The fitler is a cylindrical shaped (like a oil filter) object that is just a foot or so along the fuel line coming out of the fuel tank towards the engine. You will definatly have a good amount (1/2 gallon) of fuel leak out once you open the filter and take it off. Make sure to shake your filter out and watch for black sediment to come out of it (If nothing dark comes out, the filter is probably still good) Quote Link to comment Share on other sites More sharing options...
brake Posted December 5, 2011 Author Report Share Posted December 5, 2011 checked pressure at the rail, it was 45psi KOEO. At idle, 36psi and would spike at 45psi with throttle blips. No vacuum to the FPR maxed it out at 45psi. Regulator is good, at least. Would drop down to 34-35 and stabilize at the 36 almost immediately after the throttle snapped shut. Once I put it up on the hoist the fuel filter was almost literally staring me in the face. Despite the good fuel pressure, you could barely blow through the old fuel filter. Idle seemed to smooth out nicely with the new filter installed, though no change in PSI readings. A pretty decent amount came out of the line when I disconnected it but nothing extraordinary. thanks for the help, gentlemen! Quote Link to comment Share on other sites More sharing options...
