At 25K, I'm on my second lift pump. It's lost one pound/pressure over the last six months -- now at 15 idle, 13 cruise, 10 wot. A relative just gave me a bunch of tools and misc. parts, including one Holly Red electric pump in the box.

Wondering if I could set up the Holly Red back at the fuel tank, in line with the stock LP, to help it out. 7 psi pressure, so would it need a regulator or any other mods? Done the search here, but what I found were Holly Blues and Blacks replacing the LP completely.

If your truck idles at 15 psi now...than the red will add 7 psi i guess, so 22 PSI total...a little high but if you don't mind a new VP in the near future go for it..i wouldn't go any higher than that idling.

 

22 psi is fine for the VP at idle. It's when you start hitting at 25 and above that you have to worry. Hey Cummnzpower, that offer of staying at your place still on the table?

 

yep sure is man...gotta go to Vegas for a week, but i'll be back in town the following gimme a hollar
