Timothy Q. ★★★★★

Took about an hour to install in my 2008 Suburban, and the returnless design made it a straightforward swap—no extra lines to mess with. Idle is steady and I haven't had any fuel pressure issues since.

Steven M. ★★★★★

Swapped this into my 2012 Tahoe and the returnless design made for a clean, factory-like fit. Fuel pressure is rock solid now, even under load.

Sebastian V. ★★★★★

Took about an hour to install in my 2008 Tahoe and the returnless design made it a direct swap with no extra lines to run. Engine idles smooth and I’ve got steady pressure even under hard acceleration now.
