Replacing gas tank,needs some tips.

[pekingduck]

When reinstalling, place the blue green part 11 into the female part of the fuel line then slide the metal part of the fuel line from the pump into the rubber fuel line, You will here it click when it is seated.

Also, I use a long handle pair of needle nose pliers with a curved tip to compress the tangs on part 11

Good tip.

And make sure the #11 rubber piece is slid over the spigot before you press it back together.
