Difficulty: Intermediate · About 35 min · Dodge Ram

Replace a Dodge Ram fuel filler neck, carefully separating the quick-connect vapor line and riveting the replacement shield in place.

Steps

1. Disconnect the filler hoses

   Work in a well-ventilated area away from sparks or flames. Remove the hose clamp, release the vapor-line quick connector, and separate the rubber filler hose from the neck.

2. Remove the old neck

   Take off the fuel cap and drill out the original shield rivets carefully while wearing eye protection. Remove the filler neck without damaging adjacent hoses or wiring.

3. Install the replacement neck

   Position the new neck and secure its shield with correctly sized rivets. Reconnect the vapor line and rubber filler hose, then tighten the hose clamp.

4. Inspect the fuel connections

   Replace the cap and check that the hoses are fully seated and not kinked. After lowering the vehicle, inspect for fuel odor or leaks before starting the engine.

Check your vehicle’s repair manual for exact specifications and fit.
