How easy is installation and what tools do I need?

• Clean fuel neck of dirt before installation for secure sealing
• If stiff, inspect threads and alignment rather than forcing

Does this cap help prevent leaks and evaporation?

• Sealing design reduces fuel spillage during slopes or movement
• Lid and gasket engineered to limit vapor escape compared to a damaged cap
• Proper fitment is essential for the cap to perform as expected
