air intrusion, rear tank empty
So air intrusion became an issue again, but differently than before when it would start then die immediately. Lately it has been starting fine, running fine, and then will die after about 1/2 mile with air at the schrader valve. The front tank is about 1/4 full and the rear tank has been on E...- danda

Dash fuse panel cover clip/screw thingies
Somehow over the years the little black plastic screw twisty things that secure the fuse panel cover have gone missing. Well, I have one, missing three. These fit into a rectangular slot and then you give them a 90 twist to secure. I'm hoping someone will be able to tell me what they are...- danda

Now that my air intrusion issue is solved I've decided I will go mechanical with electric in parallel for priming only, eg hooked to...- danda

Injectors without o-rings... do any exist?
So I was looking a bit into how return lines work on other diesel engines of the same era. On the Detroit 6.5L, the injectors have two metal nipples that a return line hose just slips onto. Some hoses are made that don't even require clamps. All injectors have two nipples, so a cap is placed...- danda

A question for Injection Pump rebuilders and experts.
Calling for help from those of you that have rebuilt one of these IPs! I need info about the IP outlet "Fuel Return Regulator Housing Pressure Fitting". Ok, so some call it a "check valve" but apparently it is supposed to regulate IP fuel pressure somehow. Anyway, I'm referring to the IP...- danda

Source for new injector nozzles?
Can any of the injector rebuilders (or anyone) comment on where to obtain new nozzles these days? Also, I'd appreciate any insights on what causes an old nozzle to become leaky, and what if anything can be done about it.- danda

How is fuel pressure maintained?
Ok, I'm trying to understand how the fuel system works, especially the low pressure side. So the pump draws from the tank, through the fuel filter, and into the IP. The fuel filter housing, IP, and injectors are each connected to the return line. The return line returns back to the tank...- danda
