You need something like the e2000 pump. I have one that I used for about 2 months...I paid like 108 for it but I'd sell it for 50 bucks.

Most external mounted electric fuel pumps work better if mounted by the tank, they are pushers not pullers.

sorry about the hijack, but my dd is carbed and has an electric pump in the engine bay..at what PSI does this become an issue due to pulling?

 

[1stgenxxx]

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.
