Sinister Diesel Blue Spring Kit with Billet Spring Housing for 2003-2007 Ford Powerstroke 6.0L

The easy 30 minute install of the new updated "Blue Spring" will increase your fuel pressure back up to where it should be from the factory. Most 6.0's see an increase of 10 psi 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 does include all the O-Rings and hard parts to rebuild the fuel pressure housing.

This kit also comes with a Brand New Billet Aluminum housing to keep the regulator sprig set and to prevent leaks from the housing. This is a much thicker, stronger billet piece than the factory Cast Aluminum spring housing. The factory unit is known to leak or "weep" fuel from the sides. This kit will also help clean up the look of the factory filter housing as well.
