1994 f-250 7.3 idi factory turbo, was losing fuel prime and stalling every couple minutes, replaced the injection pump, It will idle all day but once you drive it it stalls. I have a leak in the fuel system somewhere. where do these start leaking from i know the return lines and caps are a problem area. does anyone have a afro engineered way of pressurizing the fuel system or recomendations of areas to check? Thanks in advance.
