Joseph A. ★★★★★ Oct 22, 2026

The PTFE fittings on the return kit were exactly what I needed to avoid any fuel compatibility worries, and the pump itself is a solid drop-in upgrade for my truck’s power needs.

George ★★★★★ Oct 20, 2026

The PTFE return kit is a game-changer for peace of mind—no more worrying about ethanol eating through the lines, and the pump itself fires up instantly every time. It dropped right into my 2017 Sierra without any extra wiring headaches, and fuel pressure has been rock solid since the install.

Miles ★★★★★ Oct 18, 2026

Finally got my Silverado’s fuel system sorted with this module and the PTFE return line, which feels much more durable than the rubber lines I’ve used before. Installation was straightforward once I swapped the pump over, and the truck runs strong now.
