just put in a new mallory regulater with my swapped in 350 carbed. it has a electric fuel pump and is still not idling. runs perfect for about a min or two then shuts off like its starving for fuel any help guys?!?

 

NOBODY KNOWS!?!?!? i dont see that often

 

Do you have a way to check the fuel pressure to see if it's dropping out on ya? I don't see why it would prime but not stay on.

 

well the regulater i have doesnt have a gauge. so i dont have a way. but does any1 no how to set the psi of those thnigs with out a guage>?

 

And you've got no fuel rail access ports anywhere? No schrader valve? Man, that does kinda suck... How are you even supposed to utilize an adjustable regulator without a gauge?

I only really want to know what your pressure is to see if your fuel pump is cutting out on you.

Does it abruptly stall, or get choppy, stumble, and turn off? Have you tried giving it gas when it does this to see if it keeps running or gets worse? And after it stalls, is it a hard restart?

 

after about 1 min or so it shuts off. but right when it starts it idles perfect and the whole time that it idles, i can rev it. it is a hard restart after it shuts off.

 

How is the pump wired in? If it's still running after the stall pull a line if you have to to verify that it is working. No, strike that, plumb something in to check. If it's a regular carb and the pump is set up for 7 -9 psi, put in a clear filter right before the carb so as to eliminate the fuel system to that point.

 

also id like to add, wen it jsut shuts off i push the throttle and look down the carb and i can see gas. then a push it a few more times and not much coems out.

 

With or without the pump running? If the pump is not running, that's normal as you're using just the fuel in the bowls and releiving the pressure in the system.

 

ok good. so u think i should get a guage and see where my psi is at? if so where can i get the cheapest one.
