Big Bike Parts has an alternative to replacing the entire fuel petcock assembly when your GL1500 Goldwing decides to start leaking fuel. As a less expensive alternative you can change the rubber diaphragms that have most likely given way due to age. Our fuel petcock service kit allows you to replace the sealing diaphragm, actuator diaphragm, compression spring, screws and washers with all new components. Fits Honda GL1500 1988-2000.
