The cheapest insurance on the truck. One misfuel costs more than decaling the whole yard.
What this prevents
Putting gasoline in a diesel tank, or diesel in the DEF filler. Both are expensive: a drained and flushed fuel system, a tow, and a truck off the road for days. On a DEF system it can mean replacing the pump and injector.
Why it keeps happening
Not because drivers are careless — because a rotating driver, a rental, or a yard hand fuels a truck they have not fuelled before, at night, at a pump where the handles are the same size.
What you get
DIESEL ONLY, DEF ONLY, NO GASOLINE, or your own wording. Sized from 2 inches up to 6 inches wide to fit the fill door or the filler neck surround.
Buy them in packs
Nobody orders one. Packs are priced so a whole yard costs less than one mistake, and they add nothing to shipping on an order you are already placing.
How it works
- Add to cart and type your details in the personalization box.
- We email you a proof, laid out on a vehicle, usually same day.
- You approve it. Then we cut. Nothing gets cut before you say yes.
Installs in minutes
Every decal ships pre-masked on transfer tape as one piece. Clean the surface, tape it in place, peel, squeegee, pull the tape off. Written instructions in every order.
Ships in 1-2 business days from Las Vegas, NV. Free digital proof before we cut.
