Son is broke down out of town. Has a fass150 on a 2001. Drained water from fass then next day started his truck to leave. He says it idled a few minutes then died. I have had him bleed 1, 3, 4, 5. He says no fuel out of 1 & 3 but is getting fuel from 4 & 5. Had him loosen overflow valve on vp44 and turn the key on. Fass is running but nothing is coming out of overflow valve. Now I'm really confused because how is he getting fuel to 4 & 5? Still thinking something is going on with the fass.?.? Thanks for the help!
