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.

Perfect Fit

The old cap allowed some gas fumes to escape and after a couple of days of being parked in the garage you could smell the fumes. The new cap fits tighter and does not allow any fumes to escape at all. It fit perfect.
Pros:
  • Easy To Install
Yes, I recommend this product.

Excellent price, product [...]

June 06, 2011
Other sellers have the same product for twice the price. Don't know what the other reviewer is complaining about. I normally buy all my parts from Summit Racing or Jeg's but not this time. I'll by shopping at Speedway more often. This is the same as the one I'm replacing that needed new gaskets. At Speedway's price I just replaced the whole thing.
Pros:
  • Durable
