Fuel Filler Charger/Kill Switch Port – 77-91 GMC Chevy Truck

Stop Wasting a Perfectly Good Hole.

The Fuel Filler Charging Port transforms your factory fuel filler opening into a clean, functional charging port — purpose-built for classic truck restomods and relocated fuel tank builds.

Installs directly where your old filler neck used to be. No welding. No fabrication. No headaches.

Instead of patching or plugging the opening like most builders do, the Fuel Filler Charging port gives it a job.

The Smarter Solution for Classic Truck Builders

Compatible with standard AC or Standard SAE quick-connect plugs (depending on which variation you order), this charging port is ideal for battery tenders, trickle chargers, solar charging setups, and auxiliary power access — giving you a discreet, weather-resistant power solution exactly where you need it.

Whether your truck sits in storage for months or you're running accessories on a show build, you'll have clean, reliable power access without cutting a single new hole.
