Fuel system leak and yes, it is available for inspection. My safety was at risk while I was driving the truck and smelled a very strong odor of gasoline enter the cab of the truck while I was driving with the windows rolled up. I immediately stopped the truck and got out and noticed flames coming out from underneath the bed in front of the left rear wheel, then the gas tank ignited shooting flames out like a flame thrower. The Fire Dept and the insurance company inspected it, and it was deemed a total loss. There were no warning lamps, messages, or other symptoms of a problem prior to the fire.

I detected the smell of fuel while the vehicle when it was both not running and running. I brought the truck to Banks Chevrolet in Concord NH. The high pressure fuel pump detached from its mounting flange, resulting in damage to the attaching high pressure fuel pipe causing a constant fuel leak. Dealer replaced the high pressure fuel pump and high pressure fuel pipe to resolve the concern. There is a NHTSA recall that my vehicle should have been included in, 18V358000. The GM recall number is 18188. I paid out of pocket (~$1500) to fix this safety issue when it should have been fixed initially with the recall.

The flapper just inside the fuel filler pipe has broken loose, allowing water or dust to enter, potentially causing engine failure.

I along with other people who own this model of truck with the diesel engine around 60,000 to 70,000 Miles have part number 55488542 which is the fuel feed line that rubs up against the AC line and starts to leak fuel. https://www.coloradofans.com/threads/2016-diesel-canyon-severe-fuel-leak.410108/ I along with others have numerous complaints to the Chevy dealership they said this is a common issue because of the type of line that was used and placement that it rubs up and down and since it's a diesel and vibrates a lot and basically the hose is going against the AC Muffler which is a canister and rubs it until there is a hole from rubbing. The link I added to this is one of many. This is dangerous it is fuel it is pouring out and it is in contact with hot parts of the engine

DURING SOME STARTS (IN MORNING AFTER NOT DRIVING FOR SEVERAL HOURS), THE ENGINE WILL HAVE A PULSING IDLE ~750-1000 RPM. AFTER LETTING IT SIT FOR A MINUTE TO WARM UP, I DRIVE DOWN THE ROAD. IF I AM ABLE TO DRIVE WITHOUT STOPPING, THERE WILL BE NO ISSUES. HOWEVER, IF I COME TO A STOP WITHIN 0.5 MILES OR SO, THE ENGINE WILL SHUT OFF. WHEN I TRY AND RESTART, THE ENGINE WILL STALL REPEATEDLY. THE ENGINE WILL EVENTUALLY RESTART. THERE HAVE BEEN NO CODES PRODUCED NOR ANY LIGHTS ON THE DASH BOARD. HAS HAPPENED SEVERAL TIMES.
