Hello All,

this is my first of many questions as I embark on getting my 1973 914 back on the road. I purchased the car from a friend who said it ran great before his voltage regulator began giving him issues. I was storing the car for several years for him before buying it. I know would like to see it running again.

It is a 73 1.7L with dual webers. The fuel tank was cleaned and out of the car. I went to reinstall the tank and replace the rubber lines when I noticed that both the fuel outlets on the bottom of the tank were capped off . I can not locate fuel pipe for the line to attach to the tank. I have also been told that I only need the supply line and can cap off the return line of the original fuel injection set up.

Any advice or words of wisdom would be greatly appreciated. Where can I source the fuel pipes and nuts? Auto Atlanta does not have them currently.

Thanks

If you are in there anyways, although technically not needed, carbs do benefit from having a working return line.

It helps keeping the fuel in the bowls cooler and prevents heat soak and possible hot start issues.

agree.

got a real life situation with that.
even with L jet and a return line.
have a cut down bulb on the bottom of the tank due to rhd.
when tank goes down, though it might be reading a quarter, i believe its a lot less.
and a super hot day down here, which is pretty hot, i can get to the point where even recirculating fuel warms enough after a while its starts messing with the pump due to the hot line just before the pump. temp rises in fuel in that section to critical point. and the idle starts hunting.

solution, go to gas station and fill tank well past 1/2.
fuel in tank becomes big enough heat sink.
problem goes away until next super hot day and low tank.

doesn't happen in winter.

live somewhere hot, have a return line.
maybe you can get away without one in the arctic or northern USA where it never gets hot even in summer. (IMG:style_emoticons/default/stirthepot.gif)
