@44th Miss Inf.... You mention the use of the later spec'd ep381 pump (96-up vortec) vs. the tbi spec'd pump. I thought the fuel psi was way different (<15psi/tbi vs 48-60psi/efi)??

What changes would be required to run one of these on a tbi truck?

The EP381 pump is CAPABLE of producing higher pressure, but the regulator in the tbi is what keeps the psi low. The ep381 flows more gph than the ep386.

I’ve never changed a thing, and never had an issue
