OK, went out to check on the 34 which is essentially similar to the 1933. The large vacuum take-off at the manifold heads rearward and splits on the manifold side of the engine at the very rear into two lines. (1) the painted line passes behind the engine and turns upward on the driver's side to the power brake booster valve and from there to the booster; a small takeoff from it feeds the Bijur.

The 2nd line, slightly smaller diameter and nickel plated, crosses behind the engine to the driver's side, turns forward at the base of the crankcase and connects to the feed side of the vacuum booster section of the fuel pump. The vacuum pump outlet connects via a flexible line, runs with hardline along side the frame rearwards under the fascia, and emerges at the cowl to a small copper line that runs upwards and into the A pillar to feed the wipers.

Hope this helps.
