Will a fuel pump from a Jeep 2.5L or 4.0L (something like 40psi @88pgh I think) work for a TBI'd 454? What are the numbers that a TBI 454 requires to run?

Thanks,

Ken

I'm going off memory but I think the TBI motors were 18 psi. If you ran that pump you'd need an inline fuel pressure regulator.

The throttle body has a regulator one it, so the pressure is not a problem as long as the return line is hooked up to the TB. I would wonder if it has enough volume:confused: just try it and see.
I run a 120psi import style inline pump from napa about $150 with my 454 TBI and have no problems
