I'm fairly sure that the bulb needs to be in contact with the coolant to accurately read temp. I see your problem, is there any route that the tubing can take suppose through a newly created hole in the firewall? I don't think you can move the bulb of it but you can move the plumbing and/or the gauge placement. an electronic unit is also an option.
