So while the road runner is on the lift i have been trying to figure out why the fuel tank has started leaking out of the vent tubes. The tank was replaced two years ago with a Spectra unit. It has been working perfectly but just recently when i fill it up for some reason it will spit fuel out of the vent tube like crazy.

I see that one tube goes into the frame and i think then into the trunk?

The other just goes up and has a curved end by the body.

Any thoughts on why it would start leaking out of the curved end vent tube? It has has never done this before??

Here's a couple of photos of the tubes.

Thanks for any ideas.
