The “”Blue Spring”” Fuel Pressure Regulator Repair Kit is an easy 30 minute install and will increase your fuel pressure back up to where it should be from the factory. Most 6.0’s see an increase of 10-12psi of fuel pressure. The added fuel pressure will help keep the injectors from out flowing the stock fuel pump, meaning no air in the injectors, and an injector that will live much longer. Most trucks will actually quite down a little at idle, rev up a lot quicker and with the added fuel pressure, a little quicker spool up on the turbo. The kit includes all of the O-Rings and hard parts to rebuild the fuel pressure housing.
