I was curious how a standard F.A.S.S pump without the filters would operate on my truck. I have a 04.5 GMC Duramax LLY with a Edge with attitude. Thats the biggest mod on it. I was thinking the 95 gph would be plenty. I don't know much about these pumps, would I gain? Does the pump always run, or do you shut it off during normal driving? Are they hard to hook up, or do they come with all thats needed? Let me know what you do. Thanks:ro)


04.5 GMC Sierra HD 4x4 LLY with 4-inch turbo back, AFE Cold Air, PPE EGR code blocker and plate, Edge w/Attitude, 265/75R16.:cool:

bringing back to top

- They do run all the time yes (on the trucks I have seen)
- Install was easy
- I would spend the extra money and get the full FASS that way you have the extra filtration.
