The Ford 6.7L Fuel Leak Prevention Kit (LPK) from S&S Diesel Motorsport® is the only all-in-one solution to both problems that meets and exceeds the OEM filtration specifications. Ford’s filtration is great; the problem lies with the plastic’s durability. The billet aluminum LPK solves that real problem. Yet the fuel system engineers at S&S are not going to create one problem by solving another. The decision was made to forgo the OEM fuel filter cup altogether and use a two-post mount that allows for a much larger filter that retains the factory filtration specs of 4-micron absolute at 99% efficiency and nearly double the dirt holding capacity (S&S 23 grams vs. OEM 12 grams). Fixing one leak point while leaving another does not make sense, so the aluminum Fuel Leak Prevention Fitting for the injector return comes standard with all kits. In summary, the S&S LPK prevents fuel leaks without sacrificing filtration.

These just landed so we have actual stock of them!

Fluidampr recommends to pin the damper to the crankshaft on Chevy/GM 6.6L Duramax diesel engines so they put together this kit! The kit includes press fit steel dowel pin, drill bit, and drill fixture for accurate alignment.

Features and Benefits

Secure mounting.
Recommended for Chevy/GM Duramax 6.6L

We now have inventory on hand to get these out with the dampers or if you have a damper already the kit can be sold by itself.
