I am missing the hydraulic supply tank for my 29 model U Plymouth.? Any ideas on where to obtain one and also does anyone have a picture of what it looks like and where it mounts.? Maybe I can fabricate something.
Tks, Chet? 48p15 & 1929 Model U
The brake fluid resevoir mounts on the firewall. Here is a picture of one on a 30-U. It looks a bit "off" to me so it might not be the original but it does give the general idea.

Look'n good. your engine looks very much like my 31 PA, but what is the bell crank just in front and above the starter?? Bill James
Tod,
If it is just one line going down to the Master Cylinder.., that should be pretty easy to fabricate. The 30-U had a water pump. Wow? So how well does the thermo-siphon cooling system in the 28/29 work.? My guess is not so good in hot weather or high and continuous RPMs.
Chet?
The car in my earlier post belongs to a fellow that has given me permission to post it on my Plymouth: The First Decade web site at http://www.ply33.com/
The 30-U was the first to be fitted with a water pump and a mechanical fuel pump (ending the funky vacuum tank fuel pump that ran off of oil pump suction).
I have never personally owned or driven a 1928 through 32 Plymouth so I cannot answer your question about how well the thermo-syphon cooling works.
I am new to this board, I have an early 30U with thermo and vacum fuel pump, runs great, I have a Boice Motometer on the radiator, No heating problems. I plumb my fuel pump in the the intake to keep from sucking gas into ther oil. At idle when the tank fills it will run rich but I can live with that.
The vacuum fuel canister should have a float valve inside that will keep gas from being sucked into oil pump. It least the one on my early 30U does.......
It has the float, I saw i on a site about these pumps hooking to the intake, The previus owner installed an electric wiper motor, I want to put the vacum motor back on so I can open the windsheild. When I get that done I may replume the fuel pump
This post has a lot of answers which may be off the topic. If it is the cylindrical tank for brake fluid which you need, I believe the 28 Chrysler 52 is the same, and I have an extra one somewhere.
It mounts on the firewall above the steering column and has a tee shaped handle on the top which allows fluid to be pumped into the master cylinder when needed, it is then tightened down so fluid cannot come back up when the brakes are applied.
Hi Doug, I have a 28 Ply Cpe. I have taken it on National Plymouth Meet tours in the hills of Penn. and Maine and have discovered that when mine was hooked to the intake manifold, the car's vacuum dropped so low going up long hills where you had to shift all the way down the car's vacuum tank ran out of gasoline because of not enough vacuum to pull the gas from the tank being on an incline. The Plymouth Club teck advisor told me that from the factory it was hooked to the vacuum side of the oil pump and the style of vacuum tank that was used with the gas shut off valve could not allow gas to get to the oil. My oil has never had gasoline in it. Just a thought. You can hook it where it does the best for you. Bill in Ohio
I have a question about the supply tank for the Plymouth U. Why do you need to pump brake fluid to the master cylinder when it is already gravity flow. My car has stayed filled for nearly 10 years since it was restored. Just a question. Thanks for listening.Bill
I have a 29 U and the brake fluid tank supplies fluid by gravity only. Many early vehicles with under the floor master cylinders were plumbed with remote tanks by lazy, but smart, owners who did not like the hassle involved in checking brake fluid and the ever-present possibility of dropping dirt into the open cylinder. The vent hole in the m/c cap was plugged, a 1/8" line was tapped into the cap and the tank hooked up. Gravity did the rest.
Earlier Lockheed master cylinders such as the one used in the model 52 Chrysler did not have the necessary porting which allowed the cylinder to be refilled from the reservoir each time the brakes were released. It was therefore necessary to manually open the valve on the reservoir which was a cylindrical tank mounted on the firewall just above the steering column. A few pumps of the tee handle insured the master cylinder was full, and then the tee handle was turned in to close the system. If the system had no leaks, it was not necessary to perform this task very often.
Chet, Your question was what a master cylinder reservoirs looked like for your U. Here are the pics. Tod should remove that particular photo from the site, as there are just too many misleading errors under the hood there.

Nice Car..!!!! Tks for the pictures it will help me with my never ending parts search.
