Re: testing the ALCL. poor cold start running
I just finished changing the fuel filter and the car now holds 22psi at idle.
Time to pull the fuel pumps.....

Check to see if you have the plastic clamps on the pumps. If so, I would replace w metal hose clamps and see what happens then before replacing pumps. Altho there's always the "while you're there" rule and the corollary which is "may as well".

Re: testing the ALCL. poor cold start running
Fuel pump assembly has been removed. All looks good. Before I replace the fuel pumps with ones from a suburban 454, is there a test I can do to confirm they are bad?

Re: testing the ALCL. poor cold start running
Karl,
I would replace those black plastic clamps first then put pumps back in the tank. See what ur FP is. Its easy enough to pull the pumps again if u need to replace them.

Re: testing the ALCL. poor cold start running
Are you referring to the black clamps around the hoses?

Re: testing the ALCL. poor cold start running
Yep, replace them w hose clamps. They get loose and fuel will squirt out lowering the FP.

Re: testing the ALCL. poor cold start running
One last question. How tight should the clamps be?
