Great fit, same as OEM. Great price!! Fit KW T660 with cummins.

Works great but has a cheap cap. Save your old cap and use it. Exact replacement tank.
– 
It a great product no complaints
– 
Exactly like the tank on my 2010 pete- 15 minutes to install. Been on for several months now and no leaks. I kept my old cap as the one with the tank doesnt seal well – good product and great price.
– Excellent quality product, have been very happy with the Dorman brand looks like oem quality. Everything lined up as well all bolt holes were right on spot
