Show Chrome Accessories® has an alternative to replacing the entire fuel petcock assembly when your stock unit decides to start leaking fuel. It is a lot less expensive to change the rubber diaphragms that have most likely given way due to age. Show Chrome's new Fuel Petcock Service Kit allows you to replace the sealing diaphragm, the actuator diaphragm, compression spring, screws and washers with all new components. Sold as a kit.
