If you get a fass ddrp pump you can get the relocation bracket for a few dollars extra and mount it where your carter pump is now on the frame. The carter relo bracket wont work as the fass is a bigger pump. You do have to drill holes though. On the old truck I did the big line kit with the carter pump on the rail. Switched to the ddrp pump and ran that for a few yrs, sold truck. I always had steady fuel pressure, never got below 10-11 psi. saw 18-20 at idle. The symptoms you desribe with your pump is the way my last carter went out and left me stranded in northern wv, not fun.

I just installed one in my '01 about a month ago. I wish I had installed last year. The improvement in PSI was fantastic. Pegged the gauge at 17 PSI. I relocated my factory pump about 10 years ago and have replaced it 5-6 time since then. I did use the old bracket even though I bought a new one with the pump from Geno's. I assume it's OK to mount the FASS pump horizontal. I did not use the banjo fittings since I had the fittings from the old pump that allowed me to rig everything inline. It took me about 3 hr. since I had to re-drill and tap the holes in the frame for the bracket (and it was a balmy 20* here in N. Utah) to allow enough room for the inline filter that Geno's sent with the FASS pump.
