well i don;t know where tio put this but since im running a carb i figured it'd go here. ok so when i turn my car on the guage goes up to about 1 or 2 then it will just stay there the whole time i run it. even when i adjust the regulator it doesn;t change. any help. i want this thing to show the actual pressure or at least chnge when i adjust it

 

We need more details about your fuel system set-up.

 

im using the stock pump with a aem pressure regulator and then it goes into a holley 750 carb

 

I'm not familiar with that regulator - need more details. Does it have a return port, or does it dead-head the supply to control pressure?

 

its a non return style but you can hook up the ports with one going to the carb and the other going to the return for the factory pump

 

any help someone must know

 

You mention stock pump...what stock pump are you running?

Also 1-2lbs of pressure seems low to me...I run a Carter mech. pump flowing into a Holley 650 and it reads between 5-6.

 

What type of guage are you using/basing your FP off of?? Is the car running good right now at WOT even though guage is only reading 1-2psi?? I will tell you for a fact if you only have 1-2 psi you WILL kill the engine from lack of fuel since 1-2 psi is not nearly enough to support an engine at speed and is barely enough at idle.

Have to assume your using the typical 1.5" non OR liquid filled Holley FP guage or knock off guage and all of these guages ate ambient temp sensative, meaning soon as it gets warm your readings can be anywhere from 0-burying the guage....everybody I hang with has been here done that.

 

well i got that figured out now its just the jetting and something else i need to mess with.

 

For the record, that doesn't work. You need a regulator that controls pressure by restricting the flow of the return. A dead-head style regulator will burn out the stock in-tank pump, and a dead-head style regulator with one outlet hooked to the return will simply return the majority of the flow to the tank.

So, if you "figured out" your problem by blocking off the return, your pump will be dying shortly. You either need to get a different regulator, or orifice the return such that you maintain 6 psi under max demand. Either way, you've got to have a return set up or you'll burn out the pump.

 

yeah i ended up gettin a fitting for the return and brazed it up and then cut a 16th inch hole in it so it lets some fuel but not all of it back to the return
