MGC MGC Trunk Thingies?

Hey Guys I just got my MGC into my garage and have started to inventory what is missing, what needs to be cleaned up, what needs repairs, etc. etc.

I cleaned out the trunk today and discovered a couple of what appear to be some sort of breather tubes or water connections. They are "T" shaped with one end coming out of the floor of the trunk in the upper right portion of the trunk. It appears that tubes connect to the other ends but I don't know where to connect or what to connect. They look a little like the water connections for the windshield washers. See the image below.

What are these things?

I may be wrong but think one is a fuel tank vent and the other one should have a tube extending to the vent fitting on the fuel pump.

It's interesting, I never noticed them. Probably because the boot is always full of spares. So I went and looked.
I have the T piece in the floor but not in the side wall. No clue as to whether they are vent lines or not, I think not as the gas cap
really isn't sealed.

Thanks for the info guys. I'm going to guess that one is a vent for the gas tank as when I went to lookup gas tanks in the Victoria British catalog they do indeed sell a tank that is vented and one that isn't. As for the other one being a vent for the petrol pump, that could be but I'm not sure. I'll have to look that up somewhere as well.

One is for the vent spigot at the bottom of the coil housing of a SU fuel pump, the other may be to a similar spigot on the end cover of the fuel pump. In actual practice, the only vent spigot that need to be routed into a dry space is the one at the bottom of the coil housing. The spigot on the end cover of a SU fuel pump has a check valve such that air will only pass out of the internals of the pump. See the article, SU Fuel Pump vents in the SU Fuel Pump Articles section of my Homepage, Linked in the signature block below.
Cheers,

Thanks David. I'll check it out.
