First Truck Project - 362. Need a bit of help….

Been wanting a Cabover for years and finally bought one to fiddle with. ‘84 362. Former Mobile home toter so probably not the most desirable truck given it’s low HP, relatively short WB, and a single drive axle, but good enough for what I want. it’s not a truck I will ever work, just something to mess around on and agitate my wife with!

Been sitting for years as you’d expect. Cummins BC Formula 300. Spent a solid week cleaning out tanks, replacing fuel lines that were corroded closed, put new fuel shut off solenoid on it, new filters, new starter after the old one bit the dust, etc. pressurized tank today, hit it with some ether since its only about 28 degrees today and it fired up. Idles very rough about 400 rpm’s and won’t take ANY fuel when I move the throttle level on the side of the pump. There is NO CHANGE at all.

Is a full rebuild of the pump in order here? Anything I’m missing or should try?

even at 400 rpm I had about 50lbs of oil pressure and it built air until the governor blew off and the only significant air leak I hear at this point is the parking brake on the dash…..

Trying to piece it together, but want to make sure it runs decently before I waste money on all the other things is needs…..

Thanks - tons more questions coming, but this is first step

EDIT - it is returning fuel to the tank via the return lines and I ensured clean and brand new fuel was coming from all lines

 

Just realized the large flat screw plug on top is a filter. I’m going to pull that tomorrow and see what it looks like….

 

Thank you. Yes, I saw that Oregon Diesel a few moments ago, appreciate the reference.

any special knowledge/tools to pull these pumps apart?

 

Yes, ran for about 20 minutes

 

Awesome. Thanks.


I’ll get that ordered Monday and work on getting the clutch brake cut out in the meantime. That looks like an unpleasant job……
