How To Replace A Fuel Filler Neck On Rv

1. Park the RV in a safe, level location and place wheel chocks behind each tire to prevent it from rolling while working on it.

2. Disconnect the negative battery cable using an adjustable wrench or socket wrench.

3. Remove the gas cap and fuel filler pipe retaining clip (if present) with pliers or a screwdriver, then slide the pipe off of the fuel tank filler neck.

4. Unscrew any screws that are holding down the fuel tank filler neck with a ratchet and socket set or screwdriver, then pull out all of its mounting bolts and remove it from underneath your vehicle’s body paneling (which may require removing additional trim pieces).

5. Place the new fuel tank filler neck into position, making sure that its alignment is correct before securing it down with mounting bolts (utilizing thread sealant if necessary). Reconnect any disconnected hoses/wiring harnesses at this point as well – use clamps to secure them tightly around their respective fittings on both ends of each hose/wire bundle for extra precautionary measures against leakage or future corrosion issues caused by environmental exposure over time!

  • Gather the necessary tools and supplies: a new fuel filler neck, a flathead screwdriver, pliers, and wrench set. Park your RV in an open area with plenty of room to work around it safely.
  • If possible, place it on a level surface for easier access to the fuel filler neck area. Make sure that you have appropriate safety equipment such as gloves and safety glasses before proceeding with this project.
  • Locate the existing fuel filler neck at the rear of your RV and disconnect it from both the gasoline tank and any other connecting hoses or wires using pliers or wrenches as needed.
  • Set aside any disconnected pieces for proper disposal later on in this process according to local regulations regarding hazardous materials disposal.
  • Install the new replacement fuel filler neck into position firmly securing all connections with bolts if necessary while ensuring that all seals are properly sealed up against dusts or dirt particles entering into the system.
  • Once securely installed tighten all connections by hand until they feel snug but not too tight so as not to damage them over time due to overtightening.
  • Reconnect any hoses or wiring associated with this section of your RV leaving enough slack between each connection point so that when driving vibrations occur everything remains secure without excessive strain placed upon these components.
  • Check for leaks after reconnecting everything by starting up your engine briefly then inspect underneath immediately afterward for signs of leakage which would indicate improper installation needing further attention before continuing onward.

What Causes a Fuel Filler Neck to Fail?

The fuel filler neck is an essential part of a car’s fuel system, as it serves as the conduit through which gasoline enters the vehicle’s tank.
