Aluminum 2" Male Non-Vented Fuel Cap with Combination Lock for Transfer & Auxiliary Tanks, Prevents Theft & Vandalism

Perfect fit and height. I purchased to fit through bed cover so I didn't have to remove ti fill. Perfect in every aspect. Just make sure to use yellow thread tape for diesel if that's your use.

A family member has a food truck and they left the cap at the gas station this replaced it and they have a 2003 international bus. The lock is thick and durable. There has not been any leaks. It’s a great buy for a replacement part. It was easy to assemble so the functionality is great.

These are nice fuel caps for tanks

This is NOT 2 inch NPT fit compatible as indicated in the FAQ or with Rufus. This also stated that it’s compatible with all 2 inch pipe fittings. However the item damaged the threads. Not as described or poor quality resulting in improper functionality and major loss.

The product is made nicely however the gasket material is not compatible with diesel fuel. The gasket swelled to twice its original size and allowed the cap to start leaking.*Update- Seller reached out and contacted me, said they would be looking into the issue and offered me a full refund, I declined the refund as the product is great but just had issues with the gasket, I replaced it with a compatible material.

Great aux fuel tank replacement cap. Now itl be harder to lose with the chain to keep it from falling out

Perfect for my transfer tank build. I don't much care for the lock but I didn't get this for the lock. The lock is nice in that you can set it for your own code quite easily but it could also be cut or broken quite easily. With that said, its hard to keep anyone less than honest out of anything, if they want in, they are going in. There are some pretty easy ways to make sure they don't come back out but that is not a topic for this review:) On to the actual cap assembly which is well made and threads on easily offering the ability to secure the cap. The coupling will be welded directly to the tank when I get around to building it and this will make refueling a breeze. I would get this again.
