I have replaced this tank from Mazda at least 4 times. With the Dorman lifetime warranty I hope this is the last one I have to buy. It is an exact replacement for the OEM product.

It was a perfect fit and at a good price. Probably saved myself $150 or more by ordering and installing myself. The only issue I had was that the first tank I received was damaged. It's overflow tube had been broken off, but the tank was promptly replaced. Thank you!

I bought this part on line because I could not find it anywhere else. It came on time and was in perfect condition.
