Re: FASS Pump with Driven Diesel 75psi Fuel Pressure Spring Review
Do you have the 1/2" or 5/8" draw tube in your fuel tank?
If not I would do that sooner then later. The BIGGEST killer of these pumps is still using the 3/8 or 7/16" draw tube that is OEM. I think 2005 it went to 7/16 but its still much too small the pump and thats even if your running the 125 GPH pump.
What it does is starves the pump causing cavitation and destroying the impeller. The FASS pump will become almost silent once the supply line is matching the pump head. The pump will last a lifetime if this is done as well as a proper wiring setup.
I also have the 75 PSI
relief spring in my FASS 125 GPH pump. In the fuel bowl I installed that adjustable cover plate that allows you to adjust the blue spring and dial in the fuel pressure to the injectors. I have mine set to 55-58 PSI
and it works just like they claim it will. My FASS pump is almost 5 years now and is the Titanium model.
They have very big motors on these pumps so you want to use the proper wire size which most often comes with the pump as a kit vehicle specific.
My first 2006 F250 had a weak OEM fuel pump and after installing the FASS pump I swear I gained 50 HP. But with this truck I just wanted a superior fuel pump so it went straight into current truck.
Good Luck fellas, I have nothing but good to say about the FASS Titanium line of pumps. They have been problem free with ZERO recalls, unlike what Air Dog pumps have been going through. They are on the 4th version of Air Dog and they were all recalled or pulled off the market because of design flaws with the motors pumps and even their O-rings used.
Cant go wrong putting a FASS pump in your truck as far as I'm concerned.
Good Luck fellas.......
