HS carb 4-cylinder front
The vent/overflow pipes. Short hose and clips 13 and 14 joining pipes 12 to the carb ports. Clip 16 attaching the pipes to bracket 15 with washers and nuts 17, 18 and 19. Bracket 15 looks like it should attach to the left stud hole or blanking plate bolt of the moulding or aperture for the mechanical fuel pump ... Image from MGPartsUK
... but this image shows a stud (13) for the bracket being screwed into the right-hand side of the mechanical fuel pump moulding on a 3-bearing engine. Image from Moss Europe

However this image shows what appears to be a later engine with the blanking plate, but the early breather tube for the crankcase attached to the right-hand bolt. This explains why the vent/overflow pipe bracket above is so relatively complex i.e. it was designed to fit over the breather tube. But that finished in Feb 64, so from then on the vent/overflow pipes clip could have been secured to the right-hand blanking plate bolt or stud hole, as it was on rubber bumber cars, and probably would have to be now as the bracket is NLA.

Usually the gasket between carb and air-cleaner box is 'handed' in that it must be the right way up so that as well as the bolt holes lining up the auxiliary holes in the flanges are clear as well (left). On a friends 78 I found these gaskets (right) which can be fitted either way up - brilliantly simple. But then you can go and spoil it all by installing the air-cleaner base-plate the wrong way up!
