1970MonteMotion Posted January 17, 2012 Share Posted January 17, 2012 Not sure if this goes here, but I'm in need of a sending unit that goes on the fuel tank. I need to know if the 70 model came with or without a return line. I want to say the 70's was pre all the new smog mumbo jumbo, so maybe it came factory w/o return. Anyone know for sure?

Murphy Posted January 17, 2012 Share Posted January 17, 2012 Is there 2 steel lines going into your fuel pump & one line to the carb? Or just one line in & one line out of fuel pump? If 2 in & one out you have a return line on the sending unit in the tank..... Quote Link to comment Share on other sites More sharing options...
