Kinda got carried away..... M1028 rebuild

[CARC686]

Decided to finish installing & plumbing the electric fuel pump. I used a Carter P4600HP which is a 12v, 50 gallon/hour 4.5-8 psi frame-mounted pump. I wanted to use a 24v but the P4603HD was nowhere to be found. The 12v model pulls 10 amps and will be ignition/relay-wired. Not knowing how much fuel the supercharged P400 will drink in WOT, I reached out to Bob Reynolds at Carter Technical Service for his opinion. Bob ran calculations for diesel fuel consumption in a 6.5 GM engine producing 300 HP and recommended the P4600HP. He indicated that the P4600HP might be slightly over-sized, but the fact that the fuel return line from the engine to the tank is a full 1/4" line, means that any excess fuel not needed by the engine will simply be returned to the tank. This is another reason why I incorporated a fuel pressure gauge in the custom gauge panel, so I can make sure the engine is not fuel-starved.

While I was under the truck and in the process of mounting the fuel pump to the frame, I decided to also incorporate a filter between the twin tank valve and the pump. After spending hours evaluating numerous diesel fuel filters online and at Summit, I chose a HENKYO R12T 10-micron, which is also a frame-mounted unit. The R12T also features a water separator with a clear bowl to catch any water incoming from station fuel. Both filter and water bowl are spin-on/off and the bowl has a handy threaded drain cock knob which can be operated with gloves on. In order to provide a straight-through route for the forthcoming 3" exhaust, I mounted the R12T on the cross-member under the front of the bed, between the exhaust route and the forthcoming new driveshaft route. New 3/8" rubber fuel line was used but I wanted to re-use the OEM hose clamps for nostalgic reasons. Mounting the P4600HP fuel pump on the frame caused a complication of hose routing, so I cut-off the 3/8" hard line from the engine just forward of the pump and installed a 3/8" compression x 3/8" hose barb adapter onto the hard line to connect the rubber hose. Everything worked perfectly. Before I crank the engine for the first time, I will disconnect the 4AN hose running to the fuel isolator on the firewall and energize the pump with a battery to pre-prime the system but also to run a quart or so through the filter & pump & lines to clear any small particles or debris left over from the manufacturing processes. More updates coming soon.
