2001-2004 LB7 Duramax Fuel Pressure Relief Valve Block Off Kit

Make room in the LB7 valley

The fuel pressure relief valve (FPRV) on top of the LB7 intake runner, and the factory hard lines through that part of the valley, get in the way of larger aftermarket Y-bridges and turbo inlets.

This kit lets you remove the FPRV for the clearance those parts need. The same parts come standard in every Wehrli LB7 Y-bridge kit.

Who it's for

LB7 owners installing a larger Y-bridge or turbo inlet.
