Default Help with 73 fuel lines
Can someone post diagrams of the fuel tank connection to the fuel line for a 73 AND 68 Corvette?

Thanks,
Rex

Hi Rex,
This is from my 71, but I believe the 73 tank connections are the same.
Fuel return... upper, Fuel supply...lower.
Hope this helps.
Regards,
Alan

Thanks Alan. A friend has a 68 that he rebuilt and put a 73 tank in and he needed that info.

Thanks,
Rex

Just replaced that top return line. Heard a hissing drip on the exhaust and a puddle under the right rear. The car was quickly backed out of the garage. Needless to say...all my rubber lines are new now, that was a close call.

Don't forget the vapour recovery connection on the left side of the tank. If the '68 didn't have a qjet carb, it may not have the return line on the right.

Does this line go to the charcoal filter cannister under the hood?

Both of those pictures are exactly what I have in my '74. I would think the '73 is the same.
