Has anyone installed a FASS HD system on an OBS truck before? I know the kit is made for the 99-03 but I had a buddy buy one of these and i got to do the install.
We used an Irate Diesel Regulated Return and fuel bowl delete, then used the FASS for filtration and pump.
I finished it all up today, leak free, starts and runs good. I just have a couple questions because ive never worked with a FASS before.
1) Why in the hell is this thing so loud, you can hear it when the truck is idling!
2) Is it okay to cap off the ports used to return fuel to the tank and just have a "IN" and "OUT" on the FASS? I say this because we just used the factory return from the regulator up on the motor.
Seems to be working alright, its just very very loud and almost hurts to have it running because i feel like it wants to grenade.
