Billet HPOP Reservoir Body for 1996–2003 7.3L Power Stroke

The factory cast HPOP reservoir body can crack, leak, and become another hard-to-find weak point on an aging 7.3L Powerstroke. Riffraff Diesel’s Billet HPOP Reservoir Body replaces it with a complete housing machined from a single block of 6061-T6 aluminum.
It includes stainless mounting hardware for the fuel bowl and reservoir cover, plus multiple anodized color options. Designed for 1996–2003 7.3L Power Stroke engines, it gives owners a stronger, permanent replacement while cleaning up the engine bay. A top cover is required on 1996–1997 trucks. Available in multiple colors.

Riffraff Diesel FRx Fuel Rail Crossover for 1999–2003 7.3L Power Stroke

The factory 7.3L Power Stroke fuel system deadheads at the cylinder heads, forcing trapped air through the injectors and overheating the fuel. Riffraff Diesel’s FRx Fuel Rail Crossover connects both fuel rails and adds a metered return path back to the tank. The result is a smoother, quieter idle, reduced injector cackle, better throttle response, and more consistent fuel delivery. Three included springs allow fuel-pressure settings from stock to 72 psi. Designed as a true bolt-on system, the FRx fits 1999–2003 7.3L Powerstroke trucks using the factory fuel bowl.

New Gradient Transmission Cooler for 1999–2003 7.3L Power Stroke Trucks

 

The factory 4R100 cooler can struggle once a 7.3L Powerstroke starts towing heavy, climbing grades, or making more power. The new Gradient Transmission Cooler replaces it with a direct-fit, 38-row aluminum cooler built to control transmission temperatures under load.
Its larger core and added fluid capacity help the 4R100 shed heat more effectively, while TIG-welded end tanks and factory-style mounting keep reliability at a maximum and installation straightforward. Designed for 1999–2003 Ford F-250 and F-350 trucks, it is a practical upgrade for towing, hot climates, larger tires, and modified engines as well as daily drivers.
