71 Duster Fuel vent

having the same problem?
Yes Sir. I have a 74 Duster. Finally got it running and was having ghost fuel problems. Would run great in the driveway lol. Drive a 1/4 to a mile then run outta gas. Changed the little rubber hose from tank to fuel line. Ran for a little while ( about 2 miles) then the same. Put a new fuel pump on. No change. Got a new fuel tank, new sending unit, going to bend up new engine to tank line. Just concerned about the tank venting. Not sure how to plumb it
