The ProMAXX PowerPull Ford EcoBoost 3.5L Fuel Injector Puller ProKit is precision-engineered out of solid anodized aluminum to encase the injector and to handle more pulling power. This greatly reduces damage compared to other pullers, increasing effectiveness, and boosting productivity. ProMAXX 3.5L PMXPWA115PRO is compatible with 2011-2023 Transit, 14-22 Focus, Fiesta, Ecosport, 19-23 Ranger, Bronco, Edge: Ford Part# BL3Z9F593B,DM5Z9F593-A,K2GZ-9F593-A. Fuel injector pullers currently in the market to serve 3.5L Ford EcoBoost engines involve two steel tines incorporating a slip ring to pinch the fuel injector at two contact points approximately 180 degrees apart.
