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.

Frequently Asked Questions
Q: Will this fit my Davco Fuel Pro 382 housing?
A: Yes. Compatible with both Davco Fuel Pro 380 and 382 series housings on Detroit Diesel and Cummins heavy-duty engines.
Q: Does this wrench damage the plastic collar?
A: No. Unlike generic pliers, this tool contacts only the metal vent cap, leaving the plastic collar untouched.
Q: What trucks use Davco 380/382 filters?
A: Freightliner Cascadia, Kenworth T680/T880, Peterbilt 579/389, Western Star, and International trucks with DD13/DD15/DD16 or ISX/ISX15/X15 engines.
Q: How tight should the vent cap be?
A: Hand-tight plus 1/4 turn is sufficient. Over-tightening damages the O-ring and makes future removal difficult.
Q: Can I use this for oil filter removal?
A: No. This wrench is purpose-designed for Davco fuel filter vent caps only.
