Sierra 18-7820 Fuel Pump Kit, Replaces 438555 433386, for 20-30 HP Outboards 1990-2000

The Sierra 18-7820 Fuel Pump Kit is a replacement repair kit for 20-30 HP outboard motors built from 1990 to 2000. The kit includes the gaskets needed to service the fuel pump assembly: an 18-0850 fuel pump gasket and an 18-2900 cap-to-fuel-pump gasket. This kit is used together with the 18-7800 repair kit to complete a full fuel pump rebuild on covered engines. Sierra manufactures its fuel system parts to meet or exceed the specifications of the original equipment components they replace, giving boat owners a reliable option when rebuilding a worn or leaking fuel pump instead of replacing the entire pump assembly. The 18-7820 kit is identified by Sierra part number 18-7820 and directly replaces OEM numbers 438555 and 433386. Because it is sized specifically for the 20-30 HP, 1990-2000 fitment range, boat owners should confirm their engine falls within this horsepower and model year range before ordering. The kit ships as a compact gasket set measuring 7 x 6 x 1 inches and weighing 0.05 pounds, making it an inexpensive, low-weight addition to routine outboard maintenance or a broader fuel system overhaul.
