A must-have for all Lexus SC300 owners, the PHR Bypass consists of a large #6 Stainless Steel Braided hose with metric fittings to route from the factory fuel filter to the rear of the factory fuel rail. This completely bypasses the OEM pulsation dampener unit; a severe restriction in the factory fuel system. Installation of this unit allows you to maximize the factory fuel system with less risk of a lean condition. Can also be supplied with an inline adapter to mount any electronic fuel pressure gauge sensor.
Installation is a breeze:
-Remove the factory rubber fuel line at the fuel filter using a 17mm wrench.
-Install the supplied metric fitting into the fuel filter while reusing factory crush washers.
-Attach the straight end of the #6 line to the metric fitting.
-Remove the factory fuel line at the rear of the fuel rail using a 17mm wrench and move it aside.
-Install supplied metric fitting into fuel rail while reusing the factory crush washer.
-Attach the 90 degree end of the #6 line.
-tighten all fittings and check for leaks, and you are done!
