As for the fuel heater I pulled out the plastic element back when I put the LP in. I didn't delete the housing just put the top and bottom back together. Pretty sure I put the screen back in.
I'm going to play around with the ofv adjustment more when I have time.

You might put additional strain on the lift pump but the injection pump won't be hurt until over 60psi according to quite a few big name pump shops. We've got a couple floating around at 35-40 with no issue. I see where your coming from but don't think you'll overheat the pump. After all the pump if oil lubricated and cooled.

Stay in the 35-45 range and you'll be fine. If the problem continues you'll most likely be looking a timing issue.

The bottom half is lubed by oil the plungers and barrels are lubed by fuel. Pinching off the overflow is alright as long as some fuel does return to the tank. For most street trucks 35 -40 psi of pressure is all you need.

) I've never measured how much is returned but it seems like a good bit would still be returned at 35-50. Years ago I had a discussion with the guys up at enterprise and he mentioned that anything over 50 there was a chance of actually locking the rack up. I've never heard of or seen that happen but I'd rather not take that chance. The real benefit I'm guessing is fill time is reduced so all trucks benefit, big power trucks benefit more.

Like 700+.
Still can definitely tell a difference in a stock truck or a 400hp truck but no insane power gains until big numbers.

Yes. Very big. My point (and I'm pulling this statistic straight out of my *** here) is that probably 90% of the 12V's on the road, running 60psi is as silly as a triple disc TC on a stock tranny.
