Wait you hooked it up or unhooked it? It tries to stall no matter is the booster is hooked up or not?

bigdog7373 You can check the pump by installing a pressure gauge and taping it to the cowl and watching while you drive.
Since your problem happens at idle then I highly doubt there's anything wrong with the pump. Its almost 100% positive that its carb related. Either not enough fuel or too much. Do what I said to do in my fist response and let us know what happens. It should clear up the stalling as a poorly adjusted carb or timing in the cause of this problem most of the time.

liljoe1996miller@aol I was thinking i need a new fuel pump but the fuel bowl is filling up,so will it be wiser to try feul reglator before new fuel pump?

bigdog7373 5 psi. Edelbrocks are very sensitive to fuel pressure.

liljoe1996miller@aol What iS your fuel presurre with the regulator?

bigdog7373 I have a similar setup and was having the same problem. First make sure your idle mixture is adjusted correctly. It's very easy to do.
Check your timing without vacuum advance plugged in.
Set your idle speed. What's it currently at in park and in gear?
You may need a regulator. I have a mech pump and i still use one.

75gmck25 They sell fuel pressure regulators at most parts stores, including the Edelbrock brand I think. Edelbrock documentation emphasizes the possibility of carburetor problems if you don't keep the pressure within recommended limits. A vacuum/fuel pressure gauge is very cheap, so you might want to check the pressure before you replace any parts.

With a stock mechanical pump you usually don't need a regulator because it will run at about 5 psi, but a regulator is used very frequently with electric pumps that put out more pressure.

liljoe1996miller@aol how do you change idle fuel pressure to 5psi
02-26-2013 11:38 PM
F-BIRD'88 idle fuel pressure is too high. 5psi is best. get a regulator if nessessary.
replace the fuel filter.

cadillacdave1 Check the carb float. It could be going bad and filling with gas and causing the motor to sputter and flood at red lights. While driving at speed it would be less noticeable.
