Edelbrock hands down the BEST water pumps. Not only are they lighter than standard, they actually squeeze out more water more efficiently. What does that mean? Super cool motor and much better performance. This is the second Edelbrock water pump I have purchased and installed on my trucks and I absolutely love it. This was installed on my commuter 92 k2500 7.4L. With gaskets and new fastening screws. No hose nipple was supplied that goes to the thermostat, so you'll have to reuse the old one or buy a new one separately. Do yourself and your car a favor and get it!
