The Omix Fuel Pump Base Gasket fits 1941–1945 Willys MB/GPW models and installs between the fuel pump and engine block to seal the pump mounting. Offered as an OE-style replacement that replaces OE 638737, it helps stop leaks where the pump meets the block. The part is backed by a limited five-year warranty and suits restoration of period-correct fuel systems.
