Eight (8) new fuel injector pintle tubes for 1996 thru 2002 Chevrolet GMC Vortec fuel injection systems. Some GM literature refers to these tubes as “Plastic lugs”. These pintle tubes attach to the tip of the fuel injector and are inserted into the intake manifold. Sometimes the old pintle tubes are difficult to replace and are broken during removal. They often become very brittle and crack. It is a good idea to replace these when removing and installing injectors. Free shipping to USA. Shipping cost to Canada is $8.00. Paypal accepted.
