well sammy you got it all wrong ...sorry

look good at the draw , the small tank ( 4 OZ ) is always in a full condition , only after the main ( big) tank is ampty the small tank start to drain , and you never get to it .

you will have right behind the firewall a small full fuel tank with no bubble's and with a good fule flow .

this is my 2 cent opinion
