Product Overview
A cracked, leaking, or awkward fuel-cell cap can be replaced with a billet easy-fill assembly when the tank uses the same 12-hole pattern. The 5.343-inch bolt circle and opening must be measured before fuel ever goes near the new seal.
The bolt-on assembly upgrades the standard 12-hole opening with an O-ring-sealed easy-fill cap. Fuel compatibility and cell venting must be addressed separately.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Measure the bolt circle, opening, and flange height. Confirm gasket and O-ring compatibility with the fuel and provide a proper separate vent if the cap is non-vented.
Frequently Asked Questions
Q: Is the cap vented? A: Treat it as non-vented unless the supplied cap specifically shows otherwise.
Q: Will it replace a 6-bolt cap? A: No. Six- and twelve-bolt patterns differ.
Q: Can the old gasket be reused? A: Use the correct new compatible gasket when supplied.
Q: Why measure the bolt circle? A: Fastener centers must align; outside diameter alone does not prove fit.
