I am looking for the "Red Liquid" or Substitute for the Hydrostatic Gas Gauge on my 1934 Ford Car and Info re Installing the liquid,( if I can find the Red liquid ),I have flushed and cleaned the Gauge, installed a New copper Air line from the tank to the Gauge, any info re the calibration procedure would be very helpful, an much appreciated ; thankyou RS :)
 
Hey, I live about an hour and a half south of Seattle. IF you were to stop by my place I have a bottle of Ford gauge liquid that is still as red as the day it was made, and would put some in your gauge and you would need to be careful transporting it back home but you would have the correct fluid which would not go clear after about a year like the repro stuff. It is against the law to ship this stuff so the only way I could help you would to be for you to come to me. If you plan to go to the US when this Covid slows down PM me if you want the real McCoy.
I just posted pictures in my "Misc" album of the fluid and bottle.

If you're not in a hurry take Deuce Roadster up on his offer. Top notch.
 
Rusty, You don't mention the tank unit. You should take it out and make sure it is cleaned completely, make sure all tubes and holes are clear. This tank unit also is the vent to your fuel system . I have restored lots of these and the "cups" on them are very thin brass and usually have little cracks in them you should solder up.
I usually clean what I can with Brakecleen or some strong solvent, then glass bead them with low pressure, flush with lacquer thinner then fix with solder any problems you find. When everything is as it should the gauges work fine. Since it works on air pressure, after sitting for days it may go back to zero until you move the car around and the gas sloshes around in the tank, then the fluid moves back up to the correct level.
 
Hi Deuce Roadster, Thanks so much for the offer, re the Red Liquid for the 34 Gas Gauge, Very much appreciated and Yes , I will take the Tank unit out and check and clean and repair if necessary, thanks for your offer, cheers Rusty..
 
Hi Pete, Thankyou for posting the threads to check out, re the "Hydrostatic Fuel Gauges" on the 34 Fords , very much appreciated, Rusty...
 
As Dale mentioned, the fluid is HIGHLY corrosive. I have had a couple of NOS 32 and 34 gages in their boxes that are junk. Probably from left over fluid from calibration. Boxes were toast too. When in the gauge and in very little contact with oxygen, the fluid seems to leave the gauges alone.
 
The hydrostatic line within my '34 Pickup was kinked near the fuel gauge and obstructed. A friend added a little Sta-Bil to the gauge, and since then I have always had a half tank of gasoline. The red color is still good after 10 years.
 
Interesting. I know the red dye they put in diesel fuel to mark it as 'off road' is extremely hard to get out of the system if you use in a truck tank . Wonder what that stuff is ?
