Technically, 1995 is only required to pass OBDI. It's a real hodge podge set up, but it works... pretty damn good when everything is working right!

 

How about this, crack in the metal fuel out line inside the tank there two 90's in there. No accordian on these. Straight 200psi fuel safe injector line.

 

That's what I have. I was wondering what accordion thing everyone was talking about. I went cheap when I replaced the sending unit, didn't get (i.e. couldn't afford) Delphi/Delco. I didn't think there was much to fail beside the gauge. (Which I could live with, considering the price difference) A small crack in one of those 90* bends might explain my lack of pressure and leak down problems. I didn't even think to check it when I replaced the fuel pump yesterday. Great, now I have to drain and drop the @#!$*&# tank again!

 

good thing to know tank pumps are different incase sourcing out a part in junk yard.

 

Do you have one of these, its a fuel pulse damper, 95's came with them, if you do throw it out.

 

I've never seen that part before. What does it do, and where is it located?

 

It would have been in-between the fuel pump and were it connects to the hanger in place of the short piece of fuel line they give you with the pump. It was meant to "soften" the hydrostatic shock through the system extending the life of the components. As it turns out it did more harm then good by always leaking. The consensus is that the three sections of rubber in the fuel line set -up were enough to dampen the shock.
In a nutshell if you don't have it don't worry about it, someone got rid of it before you got the truck.

 

Well, just dropped the tank again. I was hoping to find a crack or leak or something in the sending unit, but there isn't one. I plugged one end, and blew into the other until I thought I was going to blow a vein in my forehead. I even submerged it in water and blew into it hoping to find a bubble, or something. Nothing. That sending unit is air tight. I even tried blowing backwards into the pump. Nothing. Held air. I don't know what else it could be. Other than trying another regulator, I'm at a loss.

 

wow all that with no payoff must suck *****!

 

If you still have it out how about putting 12v on it and stick the whole thing in a cut open 1/2 gallon milk container filled with paint thinner and see what it does.
