FASS 95 and Airdog 100 if you go this route would be all you need, both have a lifetime warranty that sends fuel thatís not needed at the engine is returned back to the tank.
Iím partial because I actually have a liftpump installed on my truck, AD for about 6 - 7 years.
The diesel performance shop I frequent likes FASS, I prefer AirDog because they have much better customer service.
You also have Kennedy Diesel liftpump mentioned earlier, I have no experience using this product, but many have.
I would only choose between these 3, all 3 have been proven in the diesel community.
You might consider using a good diesel fuel additive if your not, also many have said bio fuel is good, we donít have bio in my state, so Iím mum on suggesting this.
