got an 83 swapping over to EFI. In over my head. Will a external fuel pump on the head work for efi if i get an aftermarket one that has for PSI?
Most external mounted electric fuel pumps work better if mounted by the tank, they are pushers not pullers.

you need like 35 or 40 psi for the fuel injection
Did you just try to answer my question cuz it had nothing to do with my question lol
I have an external electric pump that is currently pulling 2-4PSI...at what PSI does it start to hurt the pump from pulling instead of pushing?

If you are thinking about running a fuel pump off the cam like the stock carbed version I think you can forget about it, I have never seen one that will give you enough pressure.

If there is one out there I have never seen one in my 50+ years of wrenching. I have seen them mounted on the crank in drag cars feeding injectors mounted on top of blowers.
