The ProMAXX PowerPull ProKit Ford 3.5L EcoBoost PMXPWA110PRO: Compatible with Ford Injector Part #: HL3Z9F593-A (2017-2021 Ford F-150 & Lincoln Navigator 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. 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. In practice, this approach can work for those injectors that are relatively new and easy to remove. However, this approach has two issues. First, the surface area of the steel tine is very small, thereby increasing the amount of force into a tiny area and increasing the risk of damaging the plastic ring on the fuel injector. Once damaged, the injector must be replaced. The second issue is for older 3.5L EcoBoost fuel injectors that tend to be stubborn to remove easily. ProMAXX Toolâ??s 6â? Slide Hammer Accessory which delivers up to 80 PSI of pulling power for quick and easy extraction, (featured in this ProKit option) allows technicians to remove even the most stuck fuel injectors. Made entirely in the USA. ProMAXX Toolâ??s Fuel Injectors work on a variety of engines including Ford, Lincoln, Mercury & Mazda.
