2017 Ford F-350 SD fuel system problems

Filed Sep 24, 2026 · Fuel system · CA

While driving a 2017 Ford F-350 Super Duty Dually (6.7L Power Stroke) at highway speeds while towing a horse trailer containing live animals, a sudden and catastrophic failure of the secondary fuel filter occurred. The driver noticed a severe and sudden drop in fuel economy, accompanied by a strong diesel odor inside the cabin.Upon arriving safely at our destination, an inspection of the engine compartment revealed that the top plastic cap of the OEM secondary fuel filter housing had completely cracked right in the top middle. Diesel fuel was actively spraying out under extreme low-pressure system pressure (approximately 8.5 bar) all over the hot engine compartment.The pressurized diesel fuel completely saturated the front hood insulation liner, soaked the entire engine, coated the undercarriage, front left tire, all four rear dually tires, the truck bed, and the entire front face of the horse trailer. The fuel exposure has already caused multiple rubber gaskets and body-to-hood weatherstripping seals at the rear of the engine compartment to swell and degrade. This massive, pressurized fuel leak created an imminent, severe risk of a catastrophic engine fire while the vehicle was traveling at speed with a heavy load. The truck wasted roughly an entire 40-gallon tank of fuel (over $175 in extra fuel costs) during the transit due to the severity of the leak.This vehicle is a direct match for the vehicle and component population currently under active the federal safety agency Investigation PE24014. The Allevard Sogefi USA plastic fuel filter housing failed exactly as described in the federal probe due to over-pressurization. I have retained the defective cracked filter, photographic proof of the failure and subsequent vehicle/trailer damage, and fuel receipts as evidence.

I have a 2017 ford f350 diesel 6.7 and replaced the low pressure fuel pump in 2022 at about 57000 miles. Then again in July of 2026 the fuel pump has had to be replaced again at 68000 miles. I read that many 2022 ford vehicles were recalled in that year for a bad fuel pump. So I think I might have been given a bad fuel pump from that year 2022 and now its bad again. This is a know problem for fords I dont understand why there is not a recall for these pumps. Ford is been building bad pumps for a long time and are getting away with it, A fuel pump should not have to be replaced after 3 years. The work was all done at the Beach Ford Dealership in myrtle beach sc 29575.

I am filing this complaint regarding my Ford F-350, VIN [XXX], which caught fire on XXX. The truck had approximately 130,000 miles, which I consider low mileage for a properly maintained diesel Ford F-350. These trucks are known for long service life, and many Ford diesel trucks routinely remain in service for 20 years or more and exceed 250,000 miles when properly maintained. For that reason, I did not expect a sudden and catastrophic fire in a truck with only 130,000 miles. While driving, passing motorists alerted us the truck was on fire. The fire appeared to originate in the engine compartment and spread extremely rapidly. Within a very short period, the front of the truck was engulfed in flames and sustained catastrophic damage. Based on the speed and severity of the fire, I am concerned a failure in the engine compartment, fuel system, electrical system, or another vehicle component may have caused or contributed to the fire. This truck has been well maintained, kept clean, and responsibly cared for. I followed the manufacturer’s maintenance guidelines and did not expect a sudden engine-compartment fire. After the fire, I found reports of other F-350 fires and references to fire-related complaints and investigations. This raises serious concerns Ford may have known of a potential fire risk involving these trucks. This incident created major safety hazard not only to the occupants of the truck, but to other motorists and anyone nearby. Had passing drivers not alerted us, the outcome could have been far worse. The severity of the fire required a major emergency response, including multiple fire trucks and police. A vehicle fire of this magnitude presents an obvious risk of serious injury or death. I request the federal safety agency investigate Ford F-350 and vehicle fire incidents to determine whether a defect involving the fuel system, electrical system, or related parts may cause these trucks to catch fire without warning.

Driving uphill at approx 20mph near my home. Loud bang/explosion from engine or front driver-side wheel well. Red alarm flashed on instrument cluster (something like “Front Brake Failure”) and strong odor of fuel or exhaust entered cab. I immediately pulled into a pullout and put vehicle in park when I noticed flames coming from the engine compartment through the gaps in hood and wheel well. I splashed a small amount of water on the driver side front tire, but the fire continued to grow. I backed away to a safe distance and called 911. Within 5 minutes, the entire engine compartment was on fire and I captured on video explosions as the fire raged Local fire department arrived within 15 minutes, but the entire engine and cab had already been destroyed by fire. Had I been driving at high speed or with passengers, this incident could have resulted in serious burn injuries and death. Had I been driving during summer months, this incident would have caused a devastating wildfire. Had I been in traffic, I may have caused a multi-car wreck. There were absolutely no warning indicators that such a violent incident could occur. Tow truck driver said it may have been a fuel filter issue which has caused other Super Duty’s to experience sudden and catastrophic engine compartment fires. Minimal research showed me that NHSTA is investigating Ford Super Duty for this very issue. My F350 is model year 2017. I also have video of fluids dripping from the burning vehicle and the droplets are on fire which leads me to believe that leaking fuel — possibly from a cracked plastic filter — may be to blame for this incredibly dangerous incident. The vehicles remains have been searched by California Highway Patrol and the remains are currently being investigated by State Farm Auto Insurance claims experts.

On two separate occasions—May 2025 and December 2025, approximately six months apart—I experienced fuel leaks from the upper fuel filter on my 2017 F-350 while driving. Both filters had previously been replaced with genuine Ford parts. I am deeply concerned that my safety was compromised during these incidents. In both cases, diesel fuel was leaking down the engine compartment without any warning indicators or alerts on the dashboard. The only indication of a problem was the smell of fuel, which I initially assumed was external. It wasn’t until I stopped the vehicle that I discovered a steady stream of fuel leaking. The most recent occurrence happened while I was on vacation, approximately 650 miles from home. There were no prior symptoms or warnings, making it extremely difficult to detect while driving, as the smell dissipates in the wind. In my opinion, this represents a significant safety hazard. Diesel fuel streaming down a hot engine could easily result in a fire, posing a serious risk to both the driver and passengers.

Experienced CP4 pump failure!!!!! Failed because the pump was not designed for diesel fuel in the United States. And FORD puts them on trucks and Refuses to recall them knowing good and well they are not designed for diesel fuel in the United States. Is our government going to continue to allow ford to do this????

This truck had a complete fuel system replaced already once when it failed while the customer was driving. We are the next owners and didn't know it had this major failure before purchase. We know this fuel pump is an issue and Ford has active law suits against them as these pumps that they continue to put even in the new Fords and all other makes of trucks are blowing up daily. Ford sees it as a revenue stream to keep their shops busy. Fuel is highly flammable and we tow a travel trailer. I would hate to see something bad happen because they won't issue a recall. There several years that are under recall currently and our year is not one of them but it has the same pump. They should not only issue recalls on all trucks that have the known failing CP4 pump, but also give the customers the option to upgrade with the after market DCR pump. The one pump that has been the #1 best replacement option. Installing a new CP4 pump only buys Ford mote time to next failure and keeps their ships full. We spent 50k on this truck. Again, it already happened once! Let's be sure to issue recalls on ALL trucks with CP4 pumps with a real solution and not just another dangerous CP4. We don't want our truck to catch on fire while driving. Its a very big safety concern!
