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*

and of course its twice as much as the one i was planning on buying

i wonder how big a deal it is?

and on a side note, why do most return style regulators ive seen say "for use with electric fuel pump only" ?
