ok well i posted a couple days ago and did not really get any replys..this is my only and daily driver and i hate to drive it like this....


i noticed last week that sometimes when i turn the key to on, the pump wouldnt make that lound noise to get some pressure before starting like it always did. so when i crank it it wont start as fast as normal...now i have the same problem but more often and it idles at like 10.5-11 psi!!!! and i didnt even want to try WOT but if i get on it it def drops around 9 psi and when the truck is running the pump is not as loud as it was...but i can hear it rarley be loud and back to not so loud again. whats upp!!!! im screwd. can anyone help me

 

I know some people have had problems with the pumps on the fass the brushes sticking or something, a friend of mine would have to get under his and tap it with a wrench till he got it sent in for repair.

 

Depending on how old the fass is, there was an updated brush assembly that they sent me for the fass on my 99 I had. The problem is that fass has no technical support they only refer you to a dealer. Before I sold my 99 I was having another issue and they gave me 5 dealers, 3 were mail order houses with no knowledge the other 2 had stopped selling fass because of there poor dealer support. Called got 5 more same thing nobody could help. Finally someone on another message board was able to help.
