Dual tank valve,

Mine is a 93 and only the rear tank works. I get TERRIBLE gas mileage and am suspecting that the return is going to the broken font tank. BUT, the sending unit is also bad, soooooo.. when I switch it shows totally beyond empty even thought I know I put 2 gallons in it that I know of. So it is hard to tell without dropping the tank. Unless someone knows of a way.
