Questions & Answers
Is this a genuine original part?
This is a premium quality aftermarket replacement part, manufactured by leading marine component specialists to meet or exceed original equipment (OE) standards for fitment and performance.
How do I know if it is compatible?
This cap fits almost all modern 11.3L and 22L plastic portable tanks. If your tank has a coarse thread with an approximate diameter of 55mm, this is the correct replacement.
Do I need to leave the vent open when using the engine?
Yes. You should unscrew the center vent partially when the engine is running to prevent a vacuum from forming, which could cause the engine to stall. Close it tightly when transporting the tank.
