Universal Parts 50cc-150cc Vacuum Operated Fuel Pump

Restore reliable fuel delivery on your 50cc–150cc scooter or ATV with this Universal Parts vacuum-operated fuel pump. Gray die-cast aluminum body with a round diaphragm cover secured by four Torx-head screws. Three barbed fittings: brass Gas Out barb on the side, and two gray barbed fittings (Gas In and Vacuum) on the body. Two round mounting ears with 76mm center-to-center bolt spacing for direct bolt-on fitment. Operates on engine vacuum pulses — no electrical connection required.

Compatible with 4-stroke and 2-stroke engines equipped with a remote vacuum-operated fuel pump. Verify vacuum line condition before installing — a cracked or dry-rotted vacuum line will prevent the pump from drawing fuel.
