Like the product, but it's hit and miss.

May 18, 2014
I ordered a complete 3gal tank and cap two years ago for my sons dwarf car. From the get go the cap was difficult to get on and off. It finally got to the point that I basically had to destroy it to get it off. I ordered a new cap and it works great! I've got the same items in my dwarf car and have never had a problem. I like the product, the one before must have been defective. I guess it's just hit and miss!
Yes, I recommend this product.

The bolt on ring is zinc plated steel. It could easily be welded on. We suggest removing the zinc plating for a good weld.
