Get a clear line on the ip return and supply the inlet directly with a gravity fed can of fuel. That will tell you if it is the ip or the system. Look for bubbles in the ip return.

The hummer 6.2 lines will not fit. Where can I get the correct ones?

I just stuck a 20 dollar pan heater to the bottom of my oil pan with rtv. It works great for the mild climate we have here in TN. Got it at Northern Tool

How can you tell which style you have? Are all the cucv's the same? Same as the hummer? Is the straight and angle difference in the injector or things like routing around the manifold?

These injector lines have been giving me trouble for some time. I had one that was leaking slightly. I searched around here and found that it is hard to come by the old style 6.2 inj lines that I need. I purchased what I was told was the old style I needed. It was not, but bent it into...

I worked at that smyrna airport for almost 2 yrs and never saw a single cucv move.

12v holds it open. I figured it out. I feel stupid. If you read the TM on bleeding the fuel filter it labels the shut off solinoid as the aft connection. The whole time I had the pink wire and the green mixed up. If you look at the TM on changing out the engine wire harness it shows...

When it starts, it start imediatly. You think this check valve would help my dieing after 30 sec?

The pickup pump is less that a year old. I did the test in the manual where you turn the motor for 15 sec and see if you have a quart or something. I had way more that what it called for so I didnt bother putting a gauge on it. I elemenated the tank by using a different fuel source but also...

I thought by putting a clear hose on the return of the ip and not seeing any bubbles means there is not a problem with air. I am going to try to hook a fuel can directly to the inlet of the ip and see if it does anything. I will let all of you know tomorrow.

You mean bypass the pickup pump and have a can directly suply the ip using gravity? No, I have to let it sit for a while. Usually overnight. Thanks for your input.

Thats great. Maybe thats what im doing wrong. I need to get a chicken. Or goat? Tried to fix it againg today See: http://www.steelsoldiers.com/cucv/57853-i-need-troubleshooting-help-tried-everything.html

I have exhausted my troubleshooting abilities. I am an aircraft mechanic not a diesel. Please help. I had what I thought was a injector pump going out. It had low power and hard to start. So, i got a rebuilt ip off ebay. I installed it and these are the problems: -It will start after...

Its an old truck. I searched and chased my tail on similar problems. Check and double check the wires and terminals. Ricky the Redneck PO replaced a bunch of wires in mine and the terminal crimp jobs looked like a chimp did them. I fixed those and it is good.

I have 33 and get about 16mpg with a heavy foot. I dont know how acurate the speedo is but it seems to like going about 70-80, but will keep going past the numbers. I love the truck, but, maintenance is required. Maint is easy, cheap, and simple. I was forced to use it as a daily driver...

remove the injector lines. 15mm and 19mm. Make sure you mark where they go. pull off the rocker cover, scrape all the old gasket(if it has it) and rtv off, clean it, put a bead of black rtv on it and put it back on. To bleed the injector lines keep the B-nut at the injector loose and turn the...

i have a leak in the same place. Turns out it is the L/H rocker cover. Check that. Hope it is that because also check the head gasket which is right below the rocker cover.

Today I ran it with new fuel. Same problem. From looking at the manual, it seems I should pull off the water pump plate and look at the alignment marks on the injection pump gear and cam gear. As acumunro said, the temp. fuel tank ran out very quickly without the return going to it. But...

air filter is off, everything looks clear. Replaced fuel filter, cut the old one open, no microbial growth. The diesel smells like diesel. Can I hook a line from a temp tank on my roof to the inlet side of the fuel pump? Would there be enough pressure? Or is there a better way to eliminate...
