This kit comes with a fuel pressure gauge and allows the user to adjust pressure to keep a constant fuel pressure which will prolong the life of the injectors. This kit completely replaces the factory fuel filter bowl with the 10 Micron filter. Allowing you to upgrade your system with high flow fuel lines and a 6 micron canister style fuel filter that integrates right into your factory fuel lines!!! The filter block mount utilizes a hinge system for easy fuel filter replacement while giving your engine a clean upgraded look. This system is a fully functional package and does not need any additional parts to work. 3/8" inch quick disconnect tool is required for installation.
