Details:

Its just a typical 1/8 inlet fuel gauge you can source anywhere. No stripped threads or welds. There is also a fuel pressure gauge on cool curved chrome mount that i've never seen another of but the itself missing its lens and would have to be replaced. Its A really neat well put together setup with some cool parts that a couple of carb kits and little elbow grease could make big horsepower look truly awesome once again.

This has been stored for at least 10 years so the carbs will certainly need to be kitted but they open and close as should Nothing is Cracked or broken chrome looks decent I think it could cleaned up look much better. This setup has some really nice fuel lines and a front mounted log like i've never seen before, it also linkage throttle cable mount lots of anodized fittings with braided stainless. I did not clean anything. Its as found.

Very careful.
