Installation Notes
This universal sprayless connector replaces traditional tank fittings to prevent fuel spray during connection and disconnection. The female fitting attaches to 3/8" or 5/16" fuel lines. For a complete installation, it must be paired with a corresponding male tank connector (part #8838TM6, sold separately), which fits boat fuel tanks with standard 1/4" NPT fittings. For a complete kit containing both male and female connectors, please see part number 8838US6.
