Open the Dodge Ram’s fuel filler by either pulling the interior fuel-door release (for older models with a traditional cap) or by opening the exterior fuel door on capless models. Newer Rams commonly use a capless filler that doesn’t require unscrewing a gas cap.
Identify your Ram’s fueling system
Whether your Ram uses a traditional cap and tether or a capless filler determines the exact steps. Older Rams typically have a screw-on gas cap behind a fuel door, while many newer models use a capless system. To confirm, check the fuel door area or the owner’s manual; if you see a cap on the filler neck, it’s traditional, whereas a smooth filler neck with no cap indicates capless fueling.
The following guidance covers the two most common setups you’ll encounter on Dodge Ram pickups. Choose the section that matches your truck’s configuration.
Traditional gas cap
Rams with a traditional cap have a fuel door that protects a screw-on gas cap. The opening can be accessed via an interior release or by simply opening the exterior door. Follow these steps:
- Unlock the vehicle with the key fob or inside the cabin so the fuel door can be opened.
- If equipped, use the interior fuel-door release (a small lever or button near the driver’s seat or floor panel). If there is no interior release, proceed to the exterior door.
- Go to the fuel door on the rear passenger side and open it by pressing or pulling on the door as designed.
- Unscrew the gas cap by turning it counterclockwise. Set the cap aside or place it on its tether if attached.
- Insert the fuel nozzle and begin fueling as normal.
- When finished, reinsert and tighten the gas cap clockwise until it is snug. Close the fuel door securely.
Concluding: For traditional caps, you access the door, remove and reseal the cap, then close the door to complete fueling.
Capless fueling
Capless Rams eliminate the separate gas cap, though you still open a fuel door. Use these steps:
- Unlock the vehicle with the key fob or inside the cabin if needed.
- Open the fuel door by pressing on its edge or using any interior release if your model provides one; the door should pop open.
- Insert the fuel nozzle into the filler neck and fuel as you normally would. There is no cap to remove.
- Remove the nozzle after fueling and ensure the fuel door is fully closed and latched.
- Confirm the door is shut to maintain the seal and protect the filler area from dirt and moisture.
Concluding: Capless fueling simplifies the process—open the door, pump, then close. No cap removal or resealing is needed.
Troubleshooting common issues
If the fuel door won’t open or the cap won’t turn, try these quick checks: ensure the vehicle is unlocked, verify there isn’t ice or debris blocking the latch, and confirm you’re following the correct steps for your model year. For capless systems, make sure the door is fully opened before inserting the nozzle. If problems persist, consult a Dodge/Ram dealer or a qualified technician to inspect the latch, hinges, or filler neck.
Summary
Opening a Dodge Ram’s gas cap depends on whether your model uses a traditional cap or a capless fueling system. With a traditional cap, release the interior latch (or exterior door), remove and reseal the cap, and close the door. With capless fueling, simply open the fuel door and pump—there’s no cap to remove. Always ensure the door is fully closed after fueling and refer to your owner’s manual for model-specific instructions.
