TBI questions

[RBaker]

What fuel pumps are you guys running. And what should be my desired fuel pressure going to the tbi unit.

 

[rockbuggy]

Fuel Pressure should be 9-13 lbs for most TBI units. There were some Later Big Block Tbi's that ran ~30 psi with small injectors.

Whats this TBI On for an engine?

I'm running a E2000 in mine. I put a CFM technologies adjustable pressure regulator and a gauge on it. I run it at about 15 psi.

f150 with dull tanks fram pump the pesure regulater is in the injectors so it is only going to take what it needs

To whoever mentioned the 24valve pump, that's a good idea, ha. I still have the FASS off my 00.
