I put an aluminum intake edlebrock carb and a carter electronic fuel pump on my buick 350. got it started and everything but it doesn't want to idle. I didn't go through the starter with the fuel pump i just wired it direct and hooked it up to a toggle switch. It doesn't seem to lack fuel or anything if you give it a little gas but it won't idle.Im not sure if its the carb or not cause i believe that is just a bolt on piece unless i need to idle it higher a little bit. Also on the TA stage 1 intakes the heater hose bypass is mounted in the front correct. the diagram that came with it shows that thats where it is but on the original intake it is mounted towards the rear of the intake manifold and on the diagram that reads that it's for something with the transmission. what is that and do i have my heater hoses correct.I also hooked up a maual temp gauge. I switched the temperature indicator so it doesn't have the temp light hooked up to it that is on the dash but while i had it running the temp light was blinking. I appreciate any help you can give me. Thanks, John
idle john, make sure you have the right carb base gasket. the gaskets for an aluminum intake and a cast iron intake are not the same. the wrong gasket will cause the engine to suck too much air and not idle properly.
The intake is a dual plane spread bore and the gasket is like a single plaine sqaure bore. is this what you mean?
electric fuel pump if u are running an electric fuel pump , do not need a regulator to reduce the fuel pressure before it reaches the carburetor ? u need to determine what pressure the pump is generating .
I adjusted the fuel mixture screws and it seems to run fine now. the regulator will definetly be an addition. How do I know what amount of pressure to run? Is it determined by the cfm of the carb? mine is a 600cfm
fuel pump pressure pressure is should be based on the output of the mechanical fuel pump that was on your engine . u will have to check the chassis manual for your car's engine . it should list the output flow pressure . someone else on this board already has the info & can post it . come to think of it , i believe that the data was posted sometime ago on the board . fuel pressure regulators usually have a screw that allows u to vary the pressure but u usually have to place a pressure guage in line to check the pressure . there may be some out there with fixed rates . minimum fuel pressure flow rate from 350 fuel pump is 3 lbs ; on the 455 engine , fuel pump flow pressure rate is 4.5 lbs .
Give us the part # of the fuel pump, the added pressure could be causing your fuel level(float) to be higher and overfilling the bowl, give us more info......pressure had a direct effect on float height.
