Can you install a FASS system?

This engine needs a FASS pump like it needs a vertical straight pipe exhaust. If you can't get this going, then a FASS is not going to be any help.



Luck of the draw if the mechanic has a better way to get it going. He might put a couple PSI of air pressure on the fuel tank, and then bleed the air manually. Or might use a vacuum pump, or rig in a fuel pump. Or he might crank it till he kills your starter...

Well yes this FASS pump is not my solution you right I don't know why people bother posting useless info, nevertheless I run out of fuel ones and the mechanic used a vacuum pump i think cycling something and got I started after adding 30 gal fuel I didn't watch didn't want to bother him so I don't know the procedure.
I try the alternate start every 4 minutes but stopt didn't wanna kill the starter
I don't want to be installing new parts until I really know what causing the problem
I am still waiting for the roadservise an account its weekend

Thanks for spending the time with me....

Create an account on Cummins Quickserve
Once you have an account register your engine using SN


From there you will have access to the maintenance manuals. Under the service tab there is a Symptoms lookup. Type in the symptoms. If you have a way to recover fault codes there is a fault code lookup.

If this is a 325hp C8.3, there are no codes for the engine, there is no ECU, the engine has only one solenoid on the fuel injection pump control, you can tie that open with a zip tie or wire. The only engine computer is the controller for the intake heater.

Yes that solenoid is working fine

That yellow thing looks like a capacitor, I'm guessing it's related to voltage spikes from the pump operation. In the short term I don't think it's vital to the pump working. I'd hook the pump up to 12v and give it a whack with a screwdriver handle to see if it will kick on.



If you can't find a replacement, there are plenty of alternatives. I probably would NOT replace it, instead use the schrader valve to suck the air out of that filter, then relieve the pressure at the secondary filter while cranking occasionally.

You had the suction pump pulling air out the schrader valve, keep doing that till you get only fuel, then pump the priming plunger on the transfer pump, or crank the engine ten seconds, then suck more air out. Don't try to add fuel there, or put the valve core back, just put the cap on it to hold until you get it to start and warm up.
