Truck shut down on me on the way home tonight. I swung it it a parking lot and tried to started and had nothing. I'm automatically assuming its the FASS because I have hardly and priming noise when i turn the key on...its so quiet you can hardly hear it. Other thing I noticed when I turn the key on is that its only building around 5 psi under prime and takes like 30 seconds to return to zero. Do you think it could be just the inline filter, or is the pump junk? I've also heard about people swapping out the brushes but I don't know much about that...any help?

 

sounds like brushes or filter is plugged

 

Any info on how I replace the brushes?

 

I tore into the pump, and the brushes are still at a good 80%. Used a knife to scrape the carbon off the contacts and blew it out, but other than than i can't see anything wrong. Just got done putting the pump back in and nothing changed. Next thing I did was take the line off the tank pick-up and put a suction tube with a clear hose to see if I could get fuel out of the tank and I can't. So i'm thinking the pick-up is bad and I need to drop the tank and replace it? Any help guys?

 

check it first, add a hose and put some fuel in a pail, see if it runs.

 

Sending Unit ended up being bad...Truck showed a 1/4 tank of fuel and when i went to lower the tank guess what, she was bone dry. All that work for nothing. Oh well now i know. Thanks for the help.
