Fuel Injector 0445120008 Fit Duramax Fit Chevy Silverado 2001-2004.5

Impressed for the price!!

The fuel injectors were a perfect fit —installation was smooth with no issues at all.

Great value

This fuel injector works effortlessly. If instruction were included with this product people would not have problems using it. The manner in which it arrives out of the package makes it very misleading on how to use it. Take the nut and the washer completely off and remove the sleeve. Install puller into cup, make sure you slide it all the way in. Place just the nut back on and tighten puller to cup edge. Then slide sleeve back over it and put the washer on and the spare nut it comes with and tighten down until cup pops out. Takes no effort in on nut to slide cup out. Unscrew nut and remove washer, slide sleeve off and then loosen nut used to grip cup. There are flat spots to put a wrench on to hold puller while loosening the nut. Screw nut up to the top of threads and then use a hammer to hit top of puller and it will push the cup off the tool. You can just hold puller in your hand and hit it with a hammer to push sleeve off.

Works easily
