I'm going from fuel injected to a carb. I'm trying to find out if using my electric pump will supply enough fuell pressure to run the carb,

 

Need more info , You say your going from Fuel Inj. to carb, Normally a fuel inj. pump puts out way too much pressure for a Carb.. With a Carb the max pressure you want is 7 psi the min is like 4 psi . Some of your FI units put out as much as 50 psi.

 

You can buy a small universal electric pump that you can bolt on the frame rail for like $40.00 at most part stores, Your going to need some adapters for rubber fuel line to plastic , An get a new fuel filter for the car while your at it , so you dont put a strain on the new pump , an get you a inline fuse also , unless your going to try an tap off the current hot wire .
