My rubber hoses connecting the numerous vents at my fuel tank need replacing. Anyone know off the top of their head the hose diameter? Also, can the 2 that come out the back of the tank on the outside edges be replaced without dropping the tank?

Mine are leaking, but probably caused by overfilling the tank. I plan to drive the car to Daytona the day after Thanksgiving and may not get them replaced before then. Other than letting fuel vapors escape to the atmosphere and a little spillage (from overfilling?) does this hurt anything?

 

Yes you can replace them without dropping the tank. I used some 1/4" and 3/8 fuel line.
