If you have an extra f/w sep then yes, if not then I wouldn't.
Personally my truck likes B20, quieter, more fuel pressure, and mileage is the same.
BIG, I would change that FS19594 for a Baldwin BF1275. The FS is only rated for 19.82gph, where the Baldwin is rated for 120.
Im not questioning the Yoda of Filtration but is that better filtration? or better water sep, and with a stock motor would that GPH really make that much of a difference? I have never found any water in my Fuel from MT or from my BIO, but have found it when coming home from TN one time. Thanks im about ready to pick up some new filters for a service. I was told the the Fleetguard filters were the only best thing avail for my AD 100 at the time I bought them so things have changed?
Thanks BIG
The OP asked abiut B20 not B5. World of difference between them.
