My goat ('01) has been down for @ a week waiting on the FASS to come in and get put on. FINALLY got my bracket fabbed up and installed the pump this weekend and went to prime the system...air in the line. I crack #1 and have my sweet little wife crank the truck and fuel is just dripping out and I think to myself that this doesn't look good so I crack #3 and after a few seconds it comes to life...man I giggled and almost peed my pants. I just knew I was going to be out some more $$$$ for a IP but this thing just keeps trucking with 221K on it.

 

had my fass/pump 150 for almost 3 years and trouble free. 19-20psi idle.

 

I've had mine for nearly 3 yrs.But I've noticed when we travel,if we go up in altitude my fuel pressure goes down.Usually lose about 1 or 2 lbs.Wonder why??

 

Less atmospheric perssure on the fuel tank so less push to the pump and less output pressure.

 

I've had my fass 95 for a year and a half and its great, 17psi at idle, never lower than 12 wot.

 

I figured thats what it was but wasnt sure.

 

I have had my FASS pump on for about 60,000 miles with an Edge Comp box, my pressure was 19 at install, now 3 years later its 14-16 at idle and then down to 12 wot. Still some of the best money I have spent. Our trucks shouldof came with these
