On my engine, all lines from the fuel pump to carb & vacuum wipers were missing.
I got a replacement set from one of the suppliers (2 vacuum lines & 1 fuel line).
The fuel is a no-brainer, but I'm not sure which line goes from the dual action
fuel pump to the carb base and which goes to the wiper line inside the car.
I realize I can be wrong by only 50%,l but would like to get them correct before I 
get the engine running.
Thanks 
Presently, when viewed from the front of the car, I have 1 line connected to the carb
base fitting then to the left line coming from the pump. The other line comes from the
right side of the pump then to the wiper line inside the car.
Correct? Or, NO

Someone has to know this:
When facing the engine compartment...
Which outlet from  dual diaphram fuel pump goes to the back of the carb?
Or, which outlet goes to the wiper line?
Thanks
Jim

On my 56 the left one,looking from the front, goes to the wiper motor inside the car. The right one goes to the carb or intake.. It also works fine.
