HP it is possible, but not recommended. The problem with a trim gage is that it is not very accurate. A mechanical gage is extremely accurate. I did one a while back, but we used a sender we purchased from Place Diverter. I had to fabricate a bracket to mount the mechanical cable to and then trigger the arm that works the sender (much like a gas tank sender). Overall it is a fairly complicated process that I would not recommend. The other option would be to trade in your heavy duty gimbal for a regular gimbal with trim. Again not recommended.
