I have a 71 plymouth duster with a 225cc engine and my fuel pump is not working. I am having a hard time finding the correct one online. This is the original pump and it has a added line that connects to the carburetor, I believe it is a vent line. Does anyone know where I can find one or could I just go with a pump that doesn't have the 3rd line?
Thanks.

The car is equipped with the E.C.S. (evaporative control system). The original Mopar # is 3420834.

That is interesting, carb vented to the crankcase. Vent line has nothing to do with pumping the gas. Only controlling carb fumes by routing them into the crankcase and them through the PCV valve. Could actually add to crankcase dilution. Running through a charcoal canister would make sense as that is what a later design did.

Always make sure the pump's arm goes in properly. If it doesn't, you can break a camshaft.

Now I have another question. When I was taking off the fuel lines I rounded the hard metal fitting. Is there a place that I can get a new metal fuel line that runs from the fuel pump to the fuel filter?

Your best bet is a new piece of line. Trim & bend as necessary. 5/16" tubing?

I believe Fine Lines or Right Stuff does reproduce some fuel lines. They may have a new piece for your application.
