fixing fuel starvation/missfire, jd440D loader.

Just a little talk about having a missfire from fuel starvation.
Just the screen on top of the stage 1 fuel water separator/large gunk screen got plugged up. And it was progressively getting worse over 30 minutes or so. I decided to deal with it before it totally emptied the fuel system, as that can make for a serious repiming pain.

The GM Jimmy diesels use a MUI fuel system. Otherwise known as a,
((Mechanical Unit Injector)), fuel system.
.
I cant think of any other engines besides the 2 stroke Jimmy diesels that use it.
