I was driving the Pinzgauer to Burning Man via Highway 395. The engine kept dying in a way that felt exactly like flat tires — a stumble, a hesitation, then nothing. I’d stop, look around, find nothing obviously wrong, restart it, and drive on. Three times.
It wasn’t flat tires. It was fuel starvation.
The rubber milspec coating on the inside of the gas tank was peeling off in chunks, and those chunks were getting stuck in the intake sock and fuel filter, cutting off flow. The military-spec coating was doing its job — right up until it wasn’t, and then it was actively destroying the engine’s ability to function.
I worked through this with a mechanic. He was patient. He went through every analogy available:
- “You got a screw loose?”
- “Wires crossed?”
- “All stuck up?”
- “Choking?”
Each diagnosis was actually a question, dressed up in the language of the condition. We checked and ruled out each one.
Finally, he told me to go blow myself.
He meant: blow out the fuel line. Clear the obstruction mechanically. Which worked. The engine ran clean.
The fix was simple. The diagnosis took forever because the symptoms — intermittent, self-clearing, repeating — looked exactly like something in the ignition or electrical, not fuel delivery.
The Pinzgauer made it to Burning Man. Multiple times.
