ScienceofSpeed Fuel Pump & Accessory Wiring Kit - NSX, 1991-05

New high-capacity in-tank turbine fuel pumps used today (such as the Walbro 450 LPH) have higher electrical current requirements. The factory fuel pump power system is not designed to support the current draw of these pumps, which can reduce fuel pump performance.

Read this technical overview for results from testing of this product.

This kit includes a relay-powered fuse panel that includes four fused circuits for a high-capacity fuel pump and other accessories, such as a boost control solenoid. The fuse panel mounts on the included custom aluminum mounting bracket, which attaches to a factory mounting location on all years. The kit also includes the wiring and terminals in order to upgrade the wire gauge to 12 GA leading to the fuel pump hanger. The provided detailed instructions are step-by-step, with photos.
