[QUOTE="Tazza, post: 1436, member: 82"] [FONT=Arial][SIZE=2] I believe it is accessible by just lifting the cab. It may pay to remove the pickup and replace the hose that runs down inside the tank, it may have a crack in it causing it to suck air and still have fuel in the bottom. But this wouldn't explain why you can pump the primer bulb and get the machine running for about 5 mins, as it shouldn't be able to pick up any fuel if the hose was cracked........ Another way you could test for this, is to disconnect the fuel hose from the inlet to the lift pump, hold your finger on the end of the hose to stop the fuel just running out, and squeeze the bulb and see if you get any bubbles when you release your finger (do this for a while just to be sure), run the diesel out into a bucket so you can re-use it. If you have bubbles this will tell you that you have an air leak, and if your fuel is running without bubbles it could be your lift pump. Good luck![/SIZE][/FONT] [/QUOTE]
