Thanks Ross....Don't think that I haden't thought about the black sharpie, but as it were when Carlos found the time he produced some decals with the correction and it only took a few minutes to back up and replace the decal and recallabrate....Thought I would mention that I found with the dial face oil and tempature gauges that you don't want to reinstall the pointers/needles until you are set up to callabrate the gauge, with the oil gauge you would hook it up to your shop air pressure regulator and adjust the pressure regulator to a given amount then install the the pointer on your gauge at that same amount, then adjust your regulator up and down and see if the two gauges are in sink...With the tempature gauge you would put the either filled bulb in boiling water and install gauge pointer at 212 degrees...I used the instructions for the Temp. gauge repair at https://www.ply33.com/Repair/tempgauge , It is an interesting method and worked for me, I would suggest to look for a new mechanical gauge to use as a doner that has a large sensing bulb, this will give a greater pointer travel....Oh, and to complicate matters my '32 Devaux has a 3/16" asphalt loom over the capulary tube so I had my hands full to quickly install the new loom over the capulary at the same time I made the switch to the new doner.
