Whats up guys. I am needing some help here. I am looking for the cheapest place to buy a raptor 150 fuel pump and still buy from a dealer in order for my warranty to still be valid. My fuel pressure is lower than it should and I would like to replace the oem unit with an aftermarket like the raptor. I do not have enough money for the airdog and I like the easier installation of the raptor cause I would like to still keep the factory fuel filter cannister. I also heard that the airdog makes a bigger difference with higher psi common rail systems like in the 2003-up dodge diesels than the older less psi vp44 systems.
