is this the piston pump that you need to trim the valley out to get it to clear? and how do you like it, did it help with power/ MPG? i'm wanting to put an electric or mech pump on mine.

 

You have to trim the tappet cover blanket no big deal

It helped with power for sure she pulls harder and the most I can pull fuel pressure down to is 5 psi at wot no change in mpg

Where are you getting your fuel pressure readings from? Right at the pump inlet? I drilled and tapped my AFC delete in the return galley where the banjo bolt screws in. Gauge bounces everywhere, might just be a cheap gauge. I have a replacement but Haven't messed with it since. just don't know if you guys are seein where you're pulling down supply pressure or actual case pressure; or if there's really a difference between the two. That LP looks like its workin slick

Mine is at the banjo bolt on the filter head had it on the inlet side prefilter but im moving it post filter it was really tight to the cable bracket on the inlet side. And im running a snubber.

And case pressure is way higher then the 15psi when it gets going someone made a replacement for the fss that was tapped for case pressure and I believe it goes over 80psi

Sounds about right, the needle was bouncing around 40-60... Maybe higher, I think the newer gauge has a built in snubber. Sounded like a really good idea to tap my pump top . I'd install the gauge at the Airdog but the length of the run doesn't mean itd show the same pressure at the pump but thanks for the info.

Where's your boost gauge at?
