When I first got this truck, there was a fuel leak in the valley that turned out to be the pump. That got replaced along with the hoses in the valley.
Then last winter I was having problems with the truck dieing after driving less than a mile if it wasn't plugged in and the weather was @#*@*&^%$*)&*^^%%&*^%%$$^&&!!!!! COLD (like 0 to -10deg F cold). It would always restart and run great after that, but it took 3-5 cranking bursts to get it started.
The original fuel heater wire had broken, so I removed it. Thinking that the fuel was waxing, I installed the SD fuel heater because it was less prone to breaking.
Like a dummy, I couldn't leave well enough alone, so I pulled apart the regulator to clean it. But, the O-ring on the bottom got cut as I was assembling it. Next weekend I replaced the O-ring (part of an $80 kit from Ford), but that only slowed it down. Being a ******* (and quite proud of it), I slapped some JB weld on the sucker, let it dry and installed the FPR. No more leak! Hoorah!
At least, no more leak until the next winter.
Not wanting to fool with the stock regulator any more, I decided this was the straw that broke the camel's back.
A few weeks before, I got a fuel pressure gauge from ISSPRO. It showed that the fuel pulses a lot.
The stock pump on a dead cold start (-10 to about 35) would maintain about 45-50psi, and the pressure would increase with engine temperature up to about 65psi. It would hold 65psi unless I really stepped on it.
The worst part about the stock pump was that on a cold engine (running 1-3 minutes) turning 2000rpm in 2nd gear, TC locked, the FP would drop to less than 45psi. The same was true for a warm engine on a WOT blast in 2nd & 3rd gear. Never got to try it in OD with the gauge.
So here are a few pictures and most of my BOM for the system.
Keeps dual tanks:
Fuel heater and Fuel pump relays & wiring:
I used the old fuel heater wire as the power to the relay coils. This is hot in run or start. Power for the relay contacts comes from the stud on the side of the fuse box, and each wire has a 30 amp fuse, one wire for each relay.
Bracket, filters, & pump:
More to come.
