CUCV early Glow Plug burn out - What is the cause?

[Commander5993]

Not to bring up the past but back in February I mentioned to put a clear fuel line on the ip return. Blockage is easy to find. The steel line hooked to the ip line goes right under the passenger side alternator with a rubber hose connection. Can start there and see if fuel flows. Can jump back to the frame and try and get the line off the tank but that's a need a teenager thing to fit into...I don't fit in there. I think there is one rubber line on the frame for the return but I am not sure. Technically you should be able to blow air in the rubber line behind the alternator and see if air flows too. Don't hook up the the metal line on the IP. Could be the hose off the IP is bad too.

Well, guess I missed/forgot about that one

All the hoses are fairly new. But maybe it got kinked somehow or something, i don't know. The hose on the IP looks fine, I may replace all of them though. I've never had a fuel return line have a blockage, even more so when it is mostly all hard lines. But I guess thats why I didn't test it first.

I'm not doing it today, and if it is something to do with the hoses on the tank, or if the tank has to be dropped for any reason. Then I'll have to wait until I can afford to take it to a mechanic, because I don't feel like getting into that again. If I had a car lift and transmission stand or something, maybe. Worse yet, truck has a FULL tank of fuel too. Of course that can be pumped out without too much issue.

When ever I get it figured out, I'll post what the problem ended up being... unless it has nothing to do with the return lines, and it just decided to run now... nothing would surprise me. I did put a hose on the IP return and ran it into a fuel can, I know the injectors wasn't going to be able to return fuel, but I just wanted to see and the truck ran mostly fine for the 2 to 3 min test. I could hear a slight stumble in the engine sometimes, or running a bit rough. But again, nothing was returning fuel back to the tank if this is indeed the problem. We'll see.
