I guess his workers drove around with the cap off of the fuel tank on dusty roads.

Replaced the primary fuel filter which looks just like an oil filter.

Replaced the primary fuel filter again.

Opened up the secondary filter screen ( some models have two screw on filters)

For some reason my uncle won’t take this to the appropriate ‘Diesel mechanic ‘ so he is paying me to fix it-am out of my depth a bit.

Replaced the lift pump, flushed the fuel tank twice, cleaned the screen filter, pumped up the lift pump at least 150 times including bleeding air out the top relief valve, and now I think got air in the injectors. It ran about 40 seconds. Does anyone have a paddle? This canoe is sinking & it smells funny.
