Fuel tank connector hose.
 

Does anyone know what the inner diameter is for the hose that connects the two gas tanks on a 2001 coupe (not a Z06)? Mine is not leaking but it is 12 years old. I just bought this for a daily driver for probably the next 4 years. If that hose develops a leak it would be nice to have a spare handy.

Because the hose is just a straight piece I can probably find another piece of hose. I just need to know the inner diameter.
