I have a Fass 95 on my '03, it was noisy. I replaced the original relief valve spring with one about half the strength, it made the pump a lot quieter, quieter than the CC vacuum pump when it runs. Also, the engine will run with the Fass turned off. When I had the pump apart, it was like brand new inside, like it had never been used.
I want to go with fass titanium or air dog 100, which is best and can you the fuel through the stock filter? how hard is the install? '03 HO.
NO you cannot go through the stock filter. Why would you the airdog goes down to 2 microns.
Some states Have winter Fuel other don't. . Frame mounted filters Plug. . it happens here all the time. . Bio-Diesel Year round 5%.
I used the fuel at our Station in town to be honest with you I couldn't tell if it was winter blend or not.
