Piece of junk! Failed quickly
This is a piece of junk. It lasted 1 months and failed so bad my truck was stopped by the side of the road because it leaked so bad. Had to replace it by the side of the road Don't buy it!

Perfect for the price
It's costs around 90% less than the American made, so really can't complain. Budget part helped me get out of a bind. Worked as intended and still working.
