I put a new lift pump on my truck. The sticker on it said Lucas... It has what was said in the instructions to be a fuel pressure regulator screw on the top of it. I wanted to turn the pressure up some on it, but the instructions do not show which way to turn the screw. Any help please?

 

What pressure are you running now? The VE doesn't like high pressure.

 

its exactly the same as the stock lift pump. looks to be built a lot better. it just has the regulator on it
