My 32 sedan has a 33 intake manifold and carburetor. I'm getting ready to hook up the vacuum line for the windshield wipers.

My question is could someone out there please take a few photos to show what the line looks like between the firewall and the manifold. Also, I would guess that there are several loops in the line to allow for movement. What diameter are these loops and is the line ?"?

Thanks Marty

There are others on this site who are more familiar with a 32 and will chime in with better information. But the intakes on 33 are considerably different than 1932, due in part to the the change from updraft to downdraft carburetion (though there was an update kit), the use of the Stromberg Model C automatic choke, and the vacuum power brake booster. On 33-34 there is a connection on the intake manifold via a flange and hardpipe that goes behind the engine to a junction at the rear on the driver's side. From there there is a takeoff for a hose to the power brakes, a small line for the Bijur chassis lubricator. If I recall correct and I'm going to take a look in the garage, the wipers are fed directly from the vacuum booster section of the fuel pump and the line runs up the left side A pillar.

The very small line with the loops on the manifold side of the engine is the feed to the oil pressure gauge.

PS - heading out to the garage to check on the wiper vacuum line.

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.

Marty,

On the '32, loop for the vacuum line is 3" on the O.D., line is .375" O.D.

Oil pressure line is .125" O.D.

I've attached a few engine pictures.

Regards,

Dave

Dave,

Thanks for the pictures. This should give me a good start on figuring out how to run the lines on my modified intake manifold / carburetor setup.
