Product Sizing
We recommend measuring the threads and cap of your existing fill with a set of calipers for accuracy. Most marinas and auto part stores will gladly help you with this.
There are five different tank lock systems, based on size, so it is important that you order the correct size to match your existing setup.
Dealers
Along with ordering online from the Tank Lock website, the Tank Lock is also available for purchase at many boating recreation stores and marinas across the United States.
Instructions
Installing the Tank Lock takes only a matter of seconds to complete and only requires a Phillips screwdriver and standard deckfill key / L key.
Just unscrew the chain from your old fill cap and attach it to the Tank Lock with the special screw provided. Tighten into deck fill with your L key and you're all set!
