exrernal fuel pump and regulator question

[lowthreeohz]

I need an external fp and fpr for the buggy I am converting to tbi, and basically only know that ill need 35-45psi. Is there a formula to figure out how much pump I need, or since its such a small engine (suzuki g10) can I get away with most anything specd for efi/tbi?

That's a pretty common pressure requirement, most any efi inline pump should handle that along with an Rfi designed regulator. Gm tbi motors generally ran 9-13 psi so make sure whomever you order a pump from understands you're needing 35-45 psi.
