Do you ever plan to build your truck up? If not you can go with a airdog 100 or a fass 95 both are good! I have a fass 150 and I can hear it if im right beside the tank(thats where its mounted at) but nothing inside the cab or even outside. I run like 20psi at idle and 14 wot. I also have the edge juice that has alerts that will tell me when the fuel pressure gets to low which is a great feature.
