the p pump? ... a good amount more than the air dogg will put out. I have heard of over 80psi in competition trucks, for a street truck 50-60 max no real point in goin higher than that with a 12mm pump

just installed the new overflow, psi at idle is the same ( which it should be), and I have high hopes for a wot run. Its a very simple design, that I wish I had thought of and I really think it will help.

"Hi Logan, I hope you are having a great new year. Thanks for the order" I just think that says alot about a business

Help!! I have a 24v and changed the VP44 pump. The reason I say this is, my uncle and I are changing the overflow valve in his 95. We ordered a overflow valve, got it and it looked exactly like the one on my VP44 not at all like the one on his P7100. Is the replacements different? or are they suppose to look the same?

Any help is appreciated.

Jim

They may LOOK exactly the same. The p7100 has a 35psi bypass spring and the VP has a 20psi bypass. some of the older 12v had a screw-in cap on the head where the VPs all had a ball bearing pressed in the top. My new P7100 bypass has a ball bearing top.

well that didnt seem to work, so maybe it's the lift pump? Just has less power, sounded like the overflow valve, but we pinched the line like the manual says, and no difference, so we are now thinking lift pump.
