whats the most economical upgrade for a fuel pump.. i dont have alot of money but am needing to upgrade with my new injectors and programmer. all your input is appreciated.

 

Raptor 150.

Diesel Dawgs Performance

Lifetime Warranty

 

Fass, Airdog and MITUSA are the options, check the prices on all of them and then decide. If funds are tight though the last thing you want to do is add HP. Once you do this the truck is gonna cost you more money, period. Just the way it works. Gotta pay to play no matter how you look at it.
