      Construction and Appearance. This fuel pump features a billet 6061-T6 aluminum manifold to prevent porosity issues common with cast aluminum, combined with contoured CNC-machined passages for improved flow. The pump assembly includes a universal carbon steel mounting bracket and utilizes marine-grade motors and helical bronze spur gears for durability and quiet operation. OE-quality Viton seals ensure superior durability and fuel compatibility. The finish is robust, built to withstand harsh environments.
