fuel return line

Nah, CHRYSTLER-DODGE-PLYMOUTH GAS TANK SENDING UNITS >>> Classic Car Auto Parts

It's the 11th one down in the list (Part # S-CR11238). 3/8 lines x 2. I put this one in my Dart Sport.

EDIT: *DO NOT throw away your original lock ring*

The one your referring too ....S-CR11238.... I think the one your talking about the return line looks smaller .... in the picture.
