Product Description

6.0L Fuel Filter Assembly O-Ring Seal Kit  & "Blue Spring" Upgrade Kit


Fuel Filter/Fuel Regulator Assembly: This package includes the necessary O-rings and seals to service your fuel filter / fuel regulator assembly. Whenever the gaskets and seals on the the fuel filter housing are disturbed or removed, they have a chance of leaking when reassembled. Or if you already have a leak. Use this kit to fix or prevent any leaks.

"Blue Spring" Upgrade Kit: This easy install of the new updated Ford "Blue Spring" will increase your fuel pressure back up to where it should be from the factory. If your 6.0L powerstroke is suddenly going through injectors mostly on the back two cylinders #7 & #8. If you are replacing just one of these injectors more often than not it's due to the lack of fuel pressure. These injectors NEED fuel to stay lubricated and cooled, without it the needle bottoms out on the nozzle inside the injector, and quickly destroys it. Ford spec is 45p.s.i. minimum. If it's 45p.s.i. at idle it's more than likely way less than that at WOT. This spring brings it up to the lower to mid 60's at idle. Most 6.0L'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 last much longer. Most trucks will actually quiet 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 items to rebuild the fuel pressure housing. This Kit gives you everything you need without the extra parts the OEM kit makes you buy, even though some of those parts aren't usually ever needed.

Also Available: ISK812: Key Hole Gasket Separately, & ISK613: Key Hole Gasket & Blue Spring Kit w/ Spring Cup Oring Only.

  1. Random O-ring

    Posted by TJ on 17th Feb 2018

    Shipped to me super fast and overall very pleased other than in the kit I received (and I know mistakes happen) there was one O-ring in the kit that was too large to fit anything on the fuel filter assembly. I'm not talking about the one that goes on the fuel filter cap either. Luckily I have 3 different O-ring kits and was able to match up the one I was missing due to the random O-ring that was sent in my kit. Not angry by any means just giving an honest review.
