Fuel Pressure Regulator

[Soonerfan]

Sorry guys..... I'm new here and have another question about my '99
Z-71 Silverado:

Gas gauge when sitting still goes past empty and low fuel light comes on. It'll do this 5 times or more in a 20 minute drive. Took it by "a mechanic"
and he said it was something attached to the fuel pump and I had to buy a whole new fuel pump just to get this part (can't remember it's name).
Well, I did that and you probably already know.....it didn't fix the problem. THAT was an expensive trial/error!!
I took it by a Chevy dealership (I should have to that to begin with), and they told me it was the fuel pressure regulator and it's under the hood.
I got one at www.gmpartsclub.com (http://www.gmpartsclub.com) online (great price), but have no freakin' clue where it is under the hood. I'm trying to learn to do all this by myself rather than take it to a mechanic every time.
Any help on locating this thing?
Does this sound like ther right "fix"?
Thanks again.....

I've got the same problem with my 2000 Silverado. And I'm heading from Seattle to Colorado in a week... kind of worried that I won't know how much fuel I have with the guage acting up. Previously, I had a shorted wire in my truck, and the dealer never found it, but ended up moving the wires around enough that it stopped.... any chance that the wire to the tank is shorting somewhere? The guage always goes to Empty when it's not suppose to... it doesn't go to Full except when it's reading correctly.

sorry to dig up an old post but my '00 Z71 tahoe (5.7 L) did that for about a month or so, now the gage is stuck on empty. Its not the cluster, because when you start the truck up it jumps a bit, then rests at empty again.

Have you resolved your problem over the last year???

Heck of a first post, but what the hey.

I just purchased a 01 Silverado Z71 and the gauge is doing the same thing. Doesn't seem to jump around a whole lot when driving, but when sitting idle it goes nuts. When from 1/2 to empty, then went back to normal when I started to pull it out.

Anybody else encountered this?
