Thanks for everyone jumping in to help me solve the mystery as why my John Deere 6620 would only run 30 seconds or so. After I had went through everything from the tank to the injection pump and found no problems I started over again. The hand pump/plunger on the combine was leaking out the top when pumping so I replaced that. No cure. I did put a new style hand pump on. Then I was in the process of gravity feeding diesel fuel to the transfer pump on the side of the injection pump and found that I hadn't bought a long enough rubber hose to hook it up properly. So, I just threw on a new electric fuel pump and the engine works just fine. Seems like the hand pump always leaves a little air in the filters at the top. Now with the new electric pump the transfer pump seems to push the air space right out and can fill the filters entirely up. My old electric pump operated, but it must not have been building the pressure/gpm necessary. It would bubble fuel out of the pipe to the transfer pump about 3/8" to 1/2" high. But, by the time you figure what the engine is using and what the injection pump is returning to the tank the old pump just couldn't keep up I guess. Thanks again.

It would be a great day for the collies and the terrier dogs, rats and mice would be at the bottom of the stacks so the dogs, would have a busy time hunting and killing, all the corn was gathered and ricked in what we c
