Diesel acting up

[dvogtvpe]

if you want to do some diagnostics T a vacuum gauge to the suction side of the pump to measure restriction. a typical diesel system should have around 5 in. of restriction, as the primary filter collects dirt it raise's. 15 - 20 in. of restriction is already causing loss of power and running issues. if restriction is fine then you measure fuel psi on the pressure side of the pump.

Thanks again for all the good advice...I did have the filler cap removed while draining the diesel. It's pretty old fuel so I'm thinking that's a big issue. Here's a quick pic of the main topic

So I was able to get the cab unbolted and removed. This is the 1st time I've pulled the fender pan, and I'm pleasantly surprised at how clean it is underneath.











And I see why you guys suggested removing the tank and flushing it out! Look at the brown glop floating around the bottom and notice how the sides are wavy and slimy!









I've got a couple more questions.

Is there a technique to safely remove the tank bushings, or do I just pry on the fitting until it pops out?

In regards to fuel line, am I asking for regular 1/4 inch? Nothing special like fuel injection, correct?

That fuel does not look good, glad you decided to clean it out. The fuel line you want is 30R7 or 30R9. 30R7 is easier to find and should be good enough. 30r9 is rated better for bio diesel and ethanol and will last longer. I'm not sure about the tank bushings. I would get the tank in a warm place before trying anything. I would assume you need to pull the fitting out then the bushing. If you need to replace the tank bushings I have a spair set at home I bought just in case. If you need them let me know. Good luck.

the bushings are just pushed in so just pull on the 90 fitting and it will come out. heres what mine looked like when i pulled the screen out.

Thanks gentlemen, I appreciate the info...I'm finishing up things, actually just came back in to check the online manual for the steps on bleeding the air out of the fuel system. Someone in the past had crammed 1/4" fuel line on the feed side. I replaced it with 5/16", along with new 1/4" on the return side. Also hauled the fuel tank up to the car wash and cleaned it real well. Was shocked to find out how some of the nooks and crannies are sculpted perfectly to reverse the trajectory of high pressure water towards the orbital region of ones face that is inspecting things too closely haha

Oh man, yer getting sprayed in the face at the car wash?!?!? It's like 16 degrees here. Tell me it's warmer in Illinois

[PaulF]

Haha yeah its that cold here too...doesn't take long before wet fingers are useless!

It runs! And sounds stronger than I've ever heard it run before. Tomorrow I will get the pan and cab back on...now it's time to enjoys New Years with the kids/wife!

Happy New Year

Hooray!!!!
