6" Davco 380134 Fuel Filter Vent Cap Wrench for Detroit Diesel & Cummins

Davco 380134 6" Vent Cap Fuel Filter Wrench — Heavy-Duty Diesel Service Tool Changing the fuel filter on a Detroit Diesel or Cummins engine? You need a wrench that can handle the vent cap on your Davco Fuel Pro housing without slipping or damaging the plastic collar. This 6-inch Davco 380134/382 vent cap wrench from iFJF is purpose-built for professional diesel technicians and fleet mechanics who demand reliable, damage-free filter changes every time. Why This Wrench? The Davco Fuel Pro 380 and 382 series fuel filter housings use a vent cap with a plastic collar easily damaged by improvised tools. Channel-locks and strap wrenches can crack the collar, leading to expensive housing replacements. This rubber-coated vent cap wrench grips the metal vent cap securely while protecting the surrounding plastic — no scratches, no cracks, no leaks. Key Features 6-Inch Reach: Excellent leverage for stubborn vent caps while fitting tight engine bay spaces on Freightliner, Kenworth, and Peterbilt trucks. Rubber Non-Slip Coated Handle: Comfortable grip with oily or gloved hands. Won't slip during high-torque turns. Precision-Machined Jaw: CNC-machined steel jaw matches the exact Davco vent cap profile — no play, no rounding. Plastic-Safe Design: Smooth contact surfaces eliminate the risk of cracking the Davco housing collar. Heavy-Duty Steel Construction: Corrosion-resistant black oxide finish stands up to diesel and oil exposure.
