This diesel fuel injector O-Ring Kit is a new, aftermarket set. They mount to the outside of the fuel injectors and seal it from road debris and water entering into the chamber. After years of constant exposure to hot and cold temperatures, the O-rings gradually break down and deteriorate threatening the integrity of the seal. So why not replace them now with this great fitting alternative kit!
