If you need to replace your pump, you don't want to run the risk of it failing that way in the future. This Dorman OE FIX solution upgrades the pump housing and hardware to robust aluminum to help extend service life. It also has an updated circuit board design that increases reliability. This improved replacement has undergone rigorous laboratory and on-vehicle road testing, proving it matches OEM performance.
