UPDATE!!!
Christian Bros wanted $1300 if its just a LPFP job,,,, Dealer wants $2000. Gullo Ford wanted $800 for LPFuel Pump, Autozone sold a Motorcraft LPFP for $340. So I bought pump from AZ. "borrowed" the fuel line disconnect tools from AZ, and tackled the job yesterday. The access was tough with front drive shaft but the pump is on the frame rail below driver's seat. 3 nuts, 2 canon plugs, and 4 fuel lines to remove took 30 minutes. Installed new pump in 20 minutes. The old pump had garbage in it...possibly the pump **** itself or trash from tank. primed the system to remove air with 15 cycles of the ignition to ON. that's about 3 minutes of pump operation. Lots of air bubbles viewed in the clear hose on the Amazon fuel bleed kit for $30. but finally solid stream of fuel. Then it took 2 cranks and ran but very rough...Then I see a lot of white smoke out the exhaust then a couple minutes later an engine knock. I drove it and the engine light came on with wrench symbol. ***** It also wouldn't come out of Low Power Mode so I limped it back home after adding 7 gallons of diesel to tank. I check the codes. ONLY cylinder 5 misfire code. No fuel pressure codes. So after some deliberation, I started it again. Started right up, and ran beautifully--no codes. So the low power mode and wrench was from the misfire probably caused by air in the fuel line at the #5 injector. Turning truck off & restart recycles the truck out of low power mode. Obviously the smoke was unburnt fuel poured into #5. Glad I tackled it myself.
Slick
