MG MGB Technical - Trunk hoses

I am working on a 1970 MGB. In the trunk near the wiring harness inlet there are two holes. Each has a hoses coming out of the hole through a gromit and has a "T" connected. The hoses under the car are not attached to anything and there are not any hoses hooked to the top of the "T's". I do not see what these hoses were connected to on either end. What are they for?

Don,
They sound just like the breather tubes for the fuel pump. One goes to the rear, the other goes just behind the casting where the fuel lines attach. Sound like a PO has disconnected them, probably when the pump was replaced.
And yes, the top of 'T' pieces connect to nothing.

There is also a vapor canister on the left upper side of the trunk.

I finally had time to work in the garage today and looked for the attachment points on the fuel pump. I do not see or feel any. Is it possible that this fuel pump does not have the places to hook up hoses and it has some other type of breather?
Don

Don - If you have a SU fuel pump, there is one vent at the base of the coil housing, just above the flange that attaches to the pump body. Some pumps (but not all) have a second vent on the end cover. The vents get a length of hose about the size of windshield washer hose, attached to them,"T"ed together if there are two vents and the hose run through a grommet into the trunk as a source of relatively dry air. If your pump is not a SU pump, then it probably doesn't have any vents that wil attach to a hose. Cheers - Dave
