i'm mounting a os .10 with a sullivan 2 oz. slant tank in a ace j3 cub. the tubing coming out of the tank is about 1/4" lower than the carb., but the clunk in the tank is about 1" lower than the carb. what should be inline with the carb? the tubing or the clunk.
thanks

The centerline of the fuel tank should be level with the center of the carburetor or no more than about 3/8" lower.

thanks bax
