Hy Achipmunk, Classic instruments makes a sending unit, their p/n SN36, "0" ohms empty, "30" ohms full, which is what is required for your gauge. These are a high quality made in North America product, I have installed two of them so far, and no problems, they can even supply an adjustable length unit, or custom taylor one, go to their website and have a look, price is more than most catalogue stuff, but then "you get what you pay for" don't you, hope that helps.
