Oh Bad Fuel Pressure!

[JKaltenheuser]

Bought a fass last feb. Started out with great fp-15 psi. Oct. rolled around, 12-13 psi, then 7-8, then 4-5, now 0 on start up and if im lucky 4 psi after running a while... . what is wrong with my expensive fuel pump?!?! Thanks in advance.

fuel filter?

How about prefilter between pump and tank?

Everything in the tank is good, but there is no fuel coming out of the return line, and it doesnt sound like its running, this is on a 01' 24 valve, not the 12v on my sig. Anything electrical, or fixable at home type stuff been going wrong with these units?

I have heard on more than one occasion that the FASS can eat brushes in the motor. Contact the vendor you bought it from and get another set. This is usually the fix.



And if you have 0 fuel pressure, how is it even running? Are you 100% sure that the gauge is good?
