Replace the internals and wearable parts on the Fuel Pressure Regulator. This is specifically for the Billet FPR's only. However, this rebuild kit is not appropriate for the FMU's and the new valves. Any FMU made after December of 2009 will use the new rebuild kit that contains a new valve.
The kit includes new: 4 shims, 2 diaphragms, stainless steel spring, washer, needle valve, and hose barb.
Please specify needle valve type below: silver or brass. The silver and brass needle valves are not interchangeable.
