I’ve got a jet boat with two fuel tanks in the back, the fuel pump will suck fuel from one but not the other, when I disconnect the fuel line from the tee and blow into the one that works I can hear bubbling and it works fine, the other tank unfortunately when I blow into the line it creates pressure and blows gas back out at me, it does not do this with the cap open, I’ve tried switching caps and still have the same issue, so what I’m saying is my fuel pump will only suck fuel from one tank and not the other, and the other seems to be pressurizing when I blow into it, anybody ever experienced this phenomenon, Any help or info would be greatly appreciated!
