As for the fuel filter. IF your fuel shutoff at the filter works **** it off. Or pinch the line ahead of filter off with vise grips. Then take the ring off and the bowl will come out. Clean the crud out of rhe bowl and rinse with clean fuel. Put the filter and spring back like it was. Tighten the ring, replace o ring if it looks bad. You can either fill the bowl before you put it on with fuel or not. I dont. And then look on the top of the mount , above the ring. There is 2 Phillips screws. With the bowl on filter in place. Open the one on the top left, closest to upstream fuel. Open the lever or undo your pliars, open the left screw, the filter will fill with fuel and air will bleed out at screw. Levels it open till all air bubbles are gone and stop coming out at screw. Tighten it down, then go to the one right to the right of it. Do the same, fuel and air will come out till just fuel, then tighten it down when air stops coming out. Then look where the fuel line goes to the injection pump. Loosen that screw till the air stops and nothing but fuel without air bubbles comes out. Now your good. You can crank it up and not miss a beat.
Hoye has it also, I'm sure Winston or Claifornia will link you to the page that describes it with pics if you can't follow my description. If you pole around their site it's listed in some section about tech stuff, I just forget where. It might even have a link to it from the screen where you select the fuel filter from the parts diagram?
