Hello all. Finally got my first Cummins. I have been doing a lot reading, and I have a few questions. I want to get a lift pump. I hear FASS and airdog seem to be the best. Pros and cons? I also want to get gauges. I am looking at autometer and ISSPRO. Pros and cons? I hear mechanical fuel pressure gauges can be picky in the cold? Also whats the best bang for the buck for mpg. BHAF, exhaust? Any thoughts are appreciated.
