68 dart gas tank leak

1968 Dart 270 said
The seller was also telling me some have a fuel return line. I’m assuming that’s also an aftermarket thing

Fuel return can be stock on later years for smog stuff.

Spend the extra 6.00 and buy 2 lock rings and gaskets.

On my dart I had to double up in the gasket to seal it.

These videos are corny but very clear.
