Well, it was an easy fix. The 04 have a 3/8" quick connect fitting right below the fuel filter so all I bought was the tool to pop out the fuel line to the tank. I installed my fuel hose from my blue Holley pump and sucked out 15 gallons. So that is a 50/50 mix with gas and diesel. WE filled it with about 15 gallons of diesel and it cranked up with no problems. I think he needs to change the filter after this runs out.
