ScienceofSpeed Walbro 450 Billet Mounting Bracket:
The Walbro 450 LPH fuel pump is a universal design. Most vendors sell only the pump. ScienceofSpeed now offers a plug-and-play mounting solution for these fuel pumps. The factory mounting bracket is recreated out of 6061 aluminum billet CNC lathe and 4-axis CNC mill machined with a design that allows the pump to clip onto the factory fuel pump carrier. The mounting kit includes everything required for installation including CNC machined bracket, synthetic rubber noise-isolating cushion, machined aluminum base plate, stainless steel retainer ring, ethanol resistant filter sock, outlet hose, and hose clamps. Aluminum is black anodized for ethanol corrosion resistance. Kit is sold with or without pump.

Important note: this fuel pump design requires increased electrical current compared to smaller pumps. This fuel pump requires in excess of 17 amps of current for normal operation (which exceeds the recommended factory wiring capacity). Wiring to fuel pump must be upgraded. ScienceofSpeed offers complete easy fuel pump wiring kits which include terminals to terminate the fuel pump's wires directly in to the factory fuel pump carrier's electrical connectors.
