What stands out
No new NHTSA fuel system complaint has been filed on this vehicle in over 11 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering fuel system on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Fuel Spit Back During Refueling (X49 Lifetime Warranty Extension) This bulletin involves replacing the fuel tank fill tube. This new fill tube incorporates a check valve. Some customers may experience a fuel spit back condition during vehicle refueling.

The failure pattern owners describe
Owners of 2007 RAM 1500s report consistent problems filling the fuel tank. The most common complaint: fuel backs up and spills onto the ground or sprays back when the pump's auto-shutoff triggers—some owners say this happens every single fill-up, with up to half a gallon pouring out. One owner has reported this since purchase at 16,000 miles; others see it develop over the vehicle's life.
A dealership diagnosed a leaking fuel inlet valve at the weld seam and quoted $1,240 to repair. An independent mechanic identified a faulty fuel tank inlet check valve. One owner's mechanic suspected an EVAP system defect but did not pursue diagnosis. Another owner reported the fuel emissions vent broke off the tank entirely, making filling impossible; Dodge quoted $800 for a tank replacement (the dealer later quoted $4,000 elsewhere). One owner reports a pinhole leak in the tank itself. A recall for fuel shield replacement was issued for at least one vehicle, though the dealer's service delays frustrated the owner.
A small number of complaints mention the anti-siphon ball inside the filler neck getting stuck; one service department's attempt to reposition it didn't help. Across the board, owners note the truck smells of gasoline and some stopped filling the tank completely due to safety concerns. These failures appear across various mileages from nearly new to high-mileage vehicles.

Failure modes owners describe
Fuel inlet check valve failure / fuel tank inlet valve leak
Fuel backs up and overflows from the filler neck during refueling. Some owners report the fuel inlet check valve or filler neck inlet valve is defective or leaking at a weld seam, preventing fuel from entering the tank and causing spillage onto the ground instead.
When: Occurs during refueling at any point; reported at mileages ranging from 3,000 to 300,000 miles; one owner reports issue present since purchase at 16,000 miles
Symptoms owners cite: Fuel overflows from filler neck during refueling; Fuel shoots or splashes back out when pump nozzle auto-shutoff triggers; Fuel spills onto ground instead of entering tank; Back splash happens even when manually refueling slowly; Occurs every time vehicle is refueled; Gas cap warning light and service engine light illuminate
Codes mentioned: P0457
Repairs/costs cited: Dealership diagnosed fuel inlet valve leaking at weld seam; quoted repair cost of $1,240. Independent mechanic identified faulty fuel tank inlet check valve needing replacement. Another mechanic suspected defective EVAP system but did not diagnose or repair.
Recalls/TSBs owners mention: Warranty program SB-10056513-6651 denied coverage for similar failure. Manufacturer confirmed VINs were not eligible for recall on EVAP-related complaints.
Fuel tank structural failure / pinhole leak
Fuel tank develops a pinhole leak in the tank body itself, causing fuel to seep out. One owner reported a fuel tank with a small pinhole detected while vehicle was parked.
When: At 49,509 miles
Symptoms owners cite: Small pinhole visible in fuel tank while parked; Fuel seeps from pinhole
Repairs/costs cited: Authorized dealer technician diagnosed fuel tank failure and quoted replacement at $4,000. Vehicle not yet repaired at time of complaint.
Fuel emissions vent separation / fuel tank vent system failure
The fuel emissions vent or vent line breaks off or separates from the fuel tank, preventing normal venting during refueling. Tank cannot be filled because fuel spills out instead of entering.
When: Mileage not specified in complaint
Symptoms owners cite: Fuel emissions vent breaks or separates from fuel tank; Cannot fill fuel tank—gas spills all over ground; Engine light and gas cap indicator illuminates; Technician notes vent appears to have been separated for extended period
Codes mentioned: P0457
Repairs/costs cited: Dodge dealer quoted $800 for new fuel tank. Technician noted the vent should not have broken off and observed it appeared separated for a while.
Fuel filler neck anti-siphon valve blockage or failure
The plastic anti-siphon ball inside the fuel filler neck becomes stuck, blocked, or fails to operate correctly, preventing fuel from entering the tank. Fuel stops flowing after a few seconds of refueling.
When: At 91,000 miles
Symptoms owners cite: Refueling stops after a few seconds; Cannot add fuel to vehicle tank; Plastic anti-siphon ball may be stuck or blocked
Repairs/costs cited: Service department removed and reinstalled the plastic anti-siphon ball but repair was unsuccessful. Vehicle still could not be filled. No further repair attempted.
Fuel tank overfill vent failure allowing post-shutoff overflow
After the pump nozzle auto-shutoff engages (indicating tank is full), fuel continues to overflow from the tank or filler neck, spraying gasoline everywhere. Some owners report this occurs when the tank is filled beyond approximately 25 gallons in a 30-gallon tank.
When: Reported at 16,000 miles and throughout vehicle ownership
Symptoms owners cite: Fuel overflows after automatic shutoff engages at pump; Gas sprays everywhere when nozzle auto-shutoff triggers; Occurs every time tank is filled; Owner no longer feels safe filling tank completely; Truck smells like gasoline constantly; Leaks occur only when filled past 25 gallons in 30-gallon tank
Fuel shield defect or failure requiring recall
Recall notice issued for fuel shield replacement related to a fuel leak. Owner received recall but experienced long dealer wait times and limited appointment availability.
When: At 580 miles
Symptoms owners cite: Fuel leak detected
Repairs/costs cited: Recall notice stated repair would take 30 minutes to one hour. Dealer stated repair would require vehicle to be kept 3-4 days with no appointment system available; dealer stated wait time could be 3-4 months.
Recalls/TSBs owners mention: Recall issued for fuel shield replacement; recall number not provided by owner.

A quarter of owners report trouble before 74,000; a quarter make it past 110,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.

Independent shops typically charge around $1,200 for fuel system repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
