This master hose kit ties your entire hydraulic system together the right way when you’re installing the PSC PK73FDP P-Pump Conversion on a 7.3L Super Duty. Every hose in this kit is built for proper routing, clean fitment, and dependable performance under pressure.
You’re getting the full set—pump to hydroboost, hydroboost to reservoir, reservoir to pump, plus cooler lines—so everything works as one system instead of a mix-and-match setup. The lengths are dialed in for the 7.3L platform, and the included thread sealant helps make sure everything goes together without leaks or headaches.
