HS6 Carburettor Fuel Pipes

[MarkB]

Hi all

Fitted the Dolomite Sprint HS6 Carbs to a 2500s manifold on my Vitesse. Had to make up longer studs to allow for the 6mm plastic insulators. I think on the sprint and 2.5 there was just a heat shield.

Now looking at the plumbing. I have mainly played around with the SU's on the spitfire and the fuel supply to these carbs are slightly different. The main feed on these are the larger diametre pipes and believe the smaller one's are for overflow?

I presume on a sprint there is a T piece, so each carb is fed separately.

Has anybody got this set up on there car. I was considering changing the float tops with some 1500 1.5 SU ones which has an in and out on the front carb and just an supply on the second if that makes sense.

Where do the overflow pipes join to?

Thanks

On my 2.5 Vitesse with the same setup i don,t have the second outlet,overflow is by the normal little hole behind a metal tab on top of the float lid.?

the smaller pipe usually has a piece of nylon tube fitted to it to direct overflowing fuel down to the ground and away from the hot ex manifold,later spits had them I know.
