2017 Chevrolet Colorado fuel system problems

Filed Jul 4, 2026 · Fuel system · TX

There is a major fuel line leak just before the high pressure fuel pump. It appears that the fuel line aggressively rubbed against an A/C line component (looks like a muffler/canister). This rubbing created a huge hole in the high pressure fuel line, causing diesel to spray everywhere on the driver side of the engine compartment. This causes a massive safety issue due to diesel fuel uncontrollably spraying onto hot engine components. In my own research, this seems to be a known problem for GM. I believe there is a TSB published for this exact problem, but I have yet to find the document online. This needs to be an official recalled item ASAP.

2017 Chevrolet Colorado pickup with 58,000 miles. Check engine light came on. Scanner reading by a repair shop indicated a EVAP issue. I declined the $1200 repair estimate. I paid for diagnosis of problem $200. I repaired the system by "cleaning 2 filters at the beginning of the fuel tank ventilation system. The "primary filter and hose are located in a especially dusty area on the pickup truck and is prong to plugging if regularly driven on rural gravel roads. Nothing in the owner's manual indicates the service is required of this filter. FILTER SHOULD BE RELOCATED TO ENGINE BAY. Check engine light was reset and has not come back on. NOTE: This is part of the pollution equipment that stopped working properly before 10yr. or 100,00 miles.

Fuel leak in line. There is a pin hole in the line spewing fuel under pressure when running. The fuel flows down the side of the tank as I reported in Complaint Number 11587383 on May 7th, 2024. Now I have removed the bed to discover said leak. Adding picture of the leak spewing fuel from line, by "P E" lettering on the line This is a major concern as any flame near the vehicle would cause it to go up in flames. The manufacturer should correct this problem. I see no reason why this hard plastic pipe developed a hole. It is product defect.

* Smell gas and discover leaking down driver side of fuel tank after parking, so something on top. Maybe fuel pump or ?. It is available for inspection. *Fuel puddle under vehicle in parking lot. *Have not contacted dealer, just noticed and found lots of others with same issue online with the Chevy Colorado and GMC Canyon. *I am the only one who has inspected to date. *No warning of any kinds, except stepping out of truck and heavy GAS smell, and seeing a shine of color in the rain water going to parking lot drain.

Recently I had a strong gasoline smell and leak coming from the vehicle. I took my truck in for inspection, and the mechanic said the fuel pump was damaged. The mechanic took a picture of the damaged fuel pump and could not explain how this part was destroyed in this way. I was charged $639 for the repairs. Since I am currently financing the vehicle, I researched to see if this particular make and model had any recalls. Upon discovery, it happens that in 2018 there was a recall that a high-pressure fuel pump may detach from its mounting flange, possibly resulting in the pump damaging the high-pressure fuel line. I phoned the manufacturer, and they said there was a recall for this issue for specific 2017 models but not for my truck's VIN. Since my vehicle has the same problem mentioned in the recall, I would like an investigation and possible recall on this model and vin since others may have this same problem. In my opinion, Chevrolet should reimburse me in full for damages that could have taken my family, my life, or any other motorist due to the gasoline leakage and damage to the fuel.
