Item: Honda CB550K Petcock
Why You Need This: The Honda CB550 used a number of different petcocks throughout its production life. The early K sub-models used this large-bowl petcock used on a few other bikes including some CB500 and CB750 models. The best part about this petcock style is that rebuild parts are still available, and the bowl and strainer are relatively large for greater filter surface area. Throw a new gas cap seal in there and your gas tank should be ready to go.
Installation Tip: This petcock attached to the tank via two bolts accessed by removing the fuel bowl and strainer. An o-ring in an oval shaped recess seals the petcock body to the fuel tank.
