We don’t just support S&S as a brand. We run their products in our personal vehicles, our in-house builds, and every giveaway truck we put together.

S&S Diesel Motorsport

  • Billet aluminum engine-mounted fuel filter head replaces the crack-prone plastic OEM filter housing
  • All-metal Fuel Leak Prevention Fitting replaces the brittle plastic OEM injector return fitting (included with every kit)
  • Retains the factory filtration spec: 4-micron absolute at 99% efficiency
  • Nearly double the dirt holding capacity of the factory filter (S&S 23 grams vs OEM 12 grams)
  • Two-post mount accepts a larger Donaldson spin-on filter while keeping the factory mounting location
  • LPK Plus adds the chassis-mounted Donaldson replacement filter (10-micron nominal, over 40 grams of dirt holding capacity) for a complete filtration refresh in one kit
  • Perfect complement to the S&S Disaster Prevention Kit, the DCR Pump Conversion, or a completely stock fuel system
  • Fits 2011-2026 Ford F250 through F750 trucks with the 6.7L Power Stroke diesel
  • SEMA Category 4 Replacement Part
  • Made in the USA

Every 6.7L Power Stroke owner knows the two plastic failure points in the factory fuel system: the engine-mounted fuel filter housing and the injector return fitting. Ford’s filtration itself is excellent. The problem is the plastic it lives in, which gets brittle with heat cycles and eventually cracks and leaks fuel. The S&S Diesel Motorsport Ford 6.7L Fuel Leak Prevention Kit (LPK) may not be the first solution to market, but it is the correct one. It fixes the leak points while meeting and exceeding the OEM filtration specification instead of sacrificing it.

Rather than reuse the OEM fuel filter cup, the fuel system engineers at S&S went with a billet aluminum two-post mount that accepts a much larger Donaldson spin-on filter. That keeps the factory 4-micron absolute at 99% efficiency spec while packing nearly double the dirt holding capacity (23 grams vs 12 grams OEM). And because fixing one leak point while leaving another makes no sense, every kit also includes the all-metal Fuel Leak Prevention Fitting for the injector return. Both factory plastic failure points are gone in one shot.

The standard Fuel Leak Prevention Kit covers the engine-mounted side: #6.7F11-LPK for 2011-2016 trucks and #6.7F17-LPK for 2017-2026 trucks, each at $300.00 USD. The LPK Plus bundles in the chassis-mounted Donaldson replacement filter (10-micron nominal with over 40 grams of dirt holding capacity), so you get a complete filtration refresh in one kit instead of wasting money on the Ford two-filter bundle when you only need one: #6.7F11-LPK-PLUS (2011-2016) at $350.00 USD, #6.7F17-LPK-PLUS (2017-2026) at $367.00 USD, and #6.7F17-LPK-PLUS-650 for F650 and F750 trucks at $350.00 USD. S&S projects the LPK Plus will be the go-to for most trucks.

When service time comes around, grab the matching S&S LPK Replacement Filter Kit, listed separately here at Full Send Diesel. Kits are available for each year range, including LPK plus DPK versions that add the return filter for trucks also running the S&S Gen2.1 Disaster Prevention Kit.

I'm totally pleased with my purchase and all the up grades that I've done to accommodate the FSD Heat Exchanger. Everything is working good and if i could i would add another one and also add a coolant bypass.
