Dave Holstein,
What great idea ! I’m going to used something similar to your innovation on both my Shifters.
One Honda CR125 Shifter has the New Tillotson HM-1A 42mm with a double stack fuel pump that does not require a fuel return line. So on that one I’ll just
use a standard Fram GF12 filter as a mini fuel tank (magic can) directly above the carb upside down to insure a good fuel supply to the Tilly.

The second Honda CR125 Shifter has a Mikuni BN40I 38-27 40mm with its own built in return line system. So again I’ll just use a standard Fram GF12 filter as a mini fuel tank.

Good Racing Bob Horvath
