Hi all,
This is my first post so here it goes.....
I recently got a 1985 F-250 XL 4x4 with the 6.9L idi engine. I noticed when the thing ran it's exhaust was blue. To my dismay it also misfired. I did some research and found out that the injectors and or injector pump could be to blame. I removed the injection pump and had it rebuilt by Central Diesel Injection in Red Deer, Alberta. They did a wonderful job and i am quite happy with it. I ordered some re manufactured injectors and return line kit from ebay out of Pensacola Diesel. I have the pump installed and replaced the injectors and return line tees (used a Lot of Vaseline on the tees), hoses, etc. I went to start the truck, and it ran without the smoke for 2-3 minutes and abruptly died. It idled high and then the revs were up and down until it quit. I removed the fuel filter and it was only half full of fuel. this told me that there was a line leak, and air was getting in. I tightened the injector fuel caps and noticed that fuel was coming out of the tops of the tees. I've primed the filter, bled the lines and tried starting it several different times. It would run with the same results. And after trying everything that i could think of to make sure that the tees were seated correctly, fuel can still be seen coming out of the tees. I've removed them several times, re lubed and re-installed. I've gotten two different return line kits with tees, installed those, and nothing seems to be working. I've still got air getting in, and none of the tees seem to seat right. The remanufactured injectors that came were Stanadyne, not CAV england like the ones i pulled out. They looked the same and are the same size. I'm at a loss, and am wondering if its the injectors or tees. I'm getting tired of throwing money and time at it. Any input would be appreciated.
