Jekarsy Diesel Fuel Cap — Ford 4200/4800/4900 Truck

Jekarsy Non-Vented Diesel Fuel Cap with Tether Chain — Truck Replacement

Tethered diesel cap that won't roll under the truck. Replacement non-vented diesel fuel cap built for Ford 4200, 4800, and 4900 truck applications, with an integrated tether chain so the cap never falls into a puddle at the pump.

Imagine pulling into the truck stop, popping the diesel door, and the cap just *hangs there* instead of rolling into the oil-soaked concrete. You fuel up clean, twist the Jekarsy cap back on with a solid click, and roll out without that little anxiety of 'did I forget the cap on the bumper?' Small fix, real peace of mind on every fill-up.
