I took most every access panel and the seat base off the dozer and traced the fuel line all the way from the tank to the injector pump. There are no other pumps and only two filters (a twin bank) mounted on the side of the intake manifold. Both filters are new from about a month ago (this has been happening ever since I got the dozer moved to my property) and diesel is clean fresh DOT taxed stuff. I don't run it that often, but at least once or twice a month for a good 3 - 8 hour run. Sometimes I'll put 12 - 16 hours on it on a weekend.

When the dozer is level, I get a very small flow of fuel out of the line going into the injector pump, at this point the top of the tank is only about 20 inches above the injector input. When it is on any kind of incline . . . forget it. I have to remove the return line from the injectors and pressurize the tank to get the fuel up to the injector pump. It is usually easier to just chain up the blade and spin it with the kubota if I can get near to it. If the nose is down and tank up . . . bleed the injectors and go, no problem.

I'll clean all the lines and double check flow out of the bottom tank valve. Lisa is getting tired of washing jeans and sweatshirts that smell like diesel. :rolleyes:
