[QUOTE="RangerRick, post: 429350, member: 19360"] So the transfer case to transmission adapter came in a week ago and I am waiting on several clutch parts including pressure plate, clutch disc, throwout bearing, master & slave cylinder with connecting lines, a special rod end to modify the new master cylinder pivot point and some bellhousing to SAE adapter bolts. I am in the mock up stages for figuring out the motor mounts and transmission mount arrangements and also gathering some parts to complete the turbo charge tube and exhaust fittings. There should be plenty of fuel flow with the electric fuel pump I have back on the rear fuel tank cross member. It was designed to be around 18 PSI volume for a throttle body fuel injected V8 350 engine I had in the Jeep years ago. It free flows when drawn through and when powered up provides positive pressure so it should feed the P7100 Bosch fuel injection pump just fine on the Cummins engine and help as a "lift" pump even though one is not strictly required. The fuel lines were replaced years ago with stainless steel oversized tubing from a 1991 Suburban fuel system back in 2006 or 2007 that have worked with all the other engines in the past including the LM7 5.3L Vortec I had in the Jeep last. No fuel starvation and the return is also stainless steel and almost as large as the main delivery. There should be zero fuel delivery issues. The arrow tank has a draw straw with a small "sock" attached at the bottom of the pickup and the discharge for the return just flows from the top back into the tank. I pressurized the tank since it has so many dents and dings from wheeling to make sure there are no leaks. It holds pressure for several hours and no signs of leaks when it was filled with gasoline in the past. It has been thoroughly wiped clean and dried so only diesel fuel will be inside when it is refilled the next time. I am also removing the fuel fill-pipe lead restrictor from the neck and looking for a "Diesel fuel only" labeled bezel to replace the gasser one. If I can't find one I will use my stamp set as a slight branding iron to relief and color fill the words into the original or replace it with a stainless bezel and stamp it with the words neatly so it looks factory. I will also print a nice "D" fuel pump for the background in the fuel gauge with a small arrow pointing to the side where the filler is located. I think nice small touches like this will give it that "factory installed" look & feel. RR [/QUOTE]
