6.0 PowerStroke regulated return up-pipe lines - Marty's Diesel Regulated return portion

These are the 6.0 PowerStroke fuel lines that use from the back of the heads to the regulator. We offer them individually, as a pair and then as a complete set. Be sure to click on the setup that you want! On the most complete setup, we supply the fittings on the one side are 90° fittings that screw directly into the head on a 6.0 PowerStroke. The other ends go directly to the hoses that send fuel to either side of the regulator.
