Are you all running a regulator as well? If so......which one? The specs on the pump say 15-18 psi and regulator required. I've read where some are using it, but no one mentions a regulator?

 

Guess I should search a little harder! Found out that they DO have an internal pressure regulator! Anyone have any good success stories using this pump!?

 

18 psi would be just fine without a regulator. There are guys on here running way more than that. I think the regulator is only used in gas/carburator setups.

 

I'm running 2 carter pumps inline.. Have been for couple years now... 24psi idle 19 WOT

 

bnold......no regulator I take it? I've looked at all the lift pump systems till I'm blue in the face. Really would like to build my own setup and a 2mic filter from NAPA. Filters can be found almost anywhere, but I can't find any store that carries the walbro 392. A lot of the Napa stores are carrying the P4601HP pumps in stock, or can get them overnight. Just want easy to get replacement parts. That and I'm trying to save a little coin!

 

Yep no regulator... Great thing about 2 pumps is when one dies (or the harness gets unplugged in my case) you still have 14psi fuel pressure to get you where you are going...
