33 ford gas gauge
 

Can anyone tell me how the Gas gauge works on a 33 ford It has a copper line running to the back of it. I learned from an earlier post that it is hydrostatically driven via air pressure. OK but is there supposed to be a column of fluid in the gauge itself that rises on the air pressure? Also when I removed the tank to overhaul, I was wondering what the Part is directly ahead of the spreader bar is. It looks like it takes oil and is leaking on one side. Some sort of torsion unit perhaps? Any help would be appreciated.

Sounds like the part you are referring to that is leaking is a shock absorber, it possibly has had the arm removed at some stage and the body left in place.

Enclosed are writeups on how the hydrostatic gas gauge works and how to troubleshoot it.

Might consider starting a new thread on the shock question, a lot of people scan the titles for topics they are interested in.

Yes there should be dark red fluid in the glass sight tube if the gauge is working correctly.If the gauge has been inoperable you might have to remove it and clean the line and tube.On my '33 after cleaning the gauge and the sender in the tank it still did not work.The vendors sell a kit with the fluid and a new line.I replaced the line and now the gauge functions.Keep in mind that the line in that kit comes with the connection fittings but they need to be soldered once you determine and trim it to length as its at least 1.5 ft to long. .
