The Tii has a return line

The car might be or have been a tii. Fuel injection systems need return lines, carb systems don't.

My car is a 76, non Tii and it has a return line, vent line and feed line.

I was just at the salvage looking at lines - all he had were squares, but they all had return lines-

I am thinking its a smog thing - possibly only california?

I also noticed the lines were larger diameter than my '70 (which only has the send, not the return)

this was a reply post for the fuel line tread below. Sometimes that happens.
