Customer Reviews

Heater Hose Fitting - Direct Fit, Sold Individually
Picture shows 3 only 1.
Despite the picture showing 3 differing parts, this came with one. Read the description for sure. I got the actual part described and it was what I needed at a great price. I was pretty sure that I was only ordering one, yet there were 3 shown. It also shipped slow. It arrived late which put my repair on hold until it arrived. It happens.
