M916A1 fuel priming problems - primary pump

[zebedee]

Need to 'Prime Fuel System' as I have a no start situation. Trucks been standing for a while and primary fuel filter has dried!!?? No fuel comes from the sediment drain on base of #1 filter.

TM 9-2320-363-10 is not in (the TM section of) this site.

Thanks

I see them all there thanks. -20-2 says -10 is where the "Prime Fuel System" is found, but -10 is operator, manual.... I should have recognised that number, however the -10 doesn't have priming instructions, only filling...

Well it looks like the diaphragm in the primer pump - part of the "primary filter water separator adapter" #30 is not playing nice. Can't get anything out of the outlet port when manually pumping or cranking.
Do any of the mil parts dealers carry NoS Detroit spares? I am sure that the regular Freightliner or Detroit specialist will charge a pretty penny...

Could be a line or tank issue. try cracking the line out of the filter head and put a little compressed air into the fuel tank.
