Hey Guys,
I put a carberated 350 in my 89 sierra 4x4. I bought a holley bypass style fuel pressure regulator because I was planning on using the existing fuel pump thats in the tank already. Will that fuel pump work for me?
TBI fuel pump for carbs?

I would set it at 5 to 6 PSI (no more than 6)

Right on, thanks.
Gee shep, I have had trucks with carbs over 100 on 5.5 PSI. If you need more fuel you increase the feed line size to carb, not the pressure as it shortens needle seat life. More is not always better on pressure with a carb.
