Summary

■

There is a specific tool for removing the fuel tank gauge locking ring. I unfortunately do not have this tool. So I did it with the means at hand. The multigrip pliers are not perfectly suited for this operation but with a little patience they do the trick.

The gauge is fixed halfway up the fuel tank. The seal must therefore be perfect. This is why it is recommended to use a new seal (ARA1502) each time it is removed.

Required Tools

Empty the fuel tank. Either drive or siphon.

The fuel level in the tank must be below the gauge fixing hole (symbolized by the red dotted line in the 2nd photo).

Op 02

Disconnect the 2 wires from the fuel gauge power supply. Pull by hand.

Op 03

Remove the locking ring. Use the multigrip pliers.

The ring is not actually screwed on. It is just held by 3 jaws. Simply rotate it a few degrees and it will be released.

It's not really easy to rotate the ring with the multigrip pliers, but with a little application you can do it without pinching your fingers and without getting the pliers in your head.
