Description
SIERRA Johnson/Evinrude Fuel Pump Repair Kit – 18-7800 is a service kit for specified Johnson/Evinrude/OMC fuel pumps. It replaces OMC 438616 and 433519 and provides the internal repair parts required to rebuild the compatible pump assembly.
The kit is appropriate when the pump housing remains usable but the internal diaphragm/sealing components require renewal. Match the original OMC number before opening the pump, since similar Johnson/Evinrude fuel-pump bodies can use different repair kits.
