fuel tanks should have 2 exit tubes. 1 pickup and 1 vent. run a tube from the tuned pipe (for pipe pressure) to the first tank's vent. run a tube from the same tank's pickup to the second tanks vent. from the second tanks pickup attach your fuel filter. from the filter go to the carb. I guess the quick fill would go between the tuned pipe and the first tank... but i never use them.
I agree with not using a quick fill. I had one, but it caused nothing but trouble. I fill by disconnecting the fuel line at the carb. I disconnect the pressure line at the tuned pipe and watch for fuel coming out there. Then I back the pump 2 or 3 turns.
