The PowerPull Ford 6.7L Power Stroke Fuel Injector Puller from ProMAXX Tool by Milton is available in two versions: a Base Kit (No. PMXPWP200BSE) and ProKit Plus (No. PMXPWP200PROP). Both incorporate an 8mm dimple on the fork which is designed to accommodate an air-hammered-powered punch to increase efficiency, power, and precision. The punch concentrates the force and vibration of the air hammer to vibrate and shock the fuel injector out. The ProKit Plus includes both a 11” punch as well as a 6” slide hammer to deliver more power by attaching directly to the fuel line port. Made in the USA.
