I think Fine Lines makes them.Depends on the car.There is another company that makes lines also but I cant remember the name.You could just get some bulk tuming and make them.Unless its a 100 point resto thats the cheapest route.Rocky

Why is it that the discharge side needs to be smaller than the low pressure suction side??
Because gasoline is very hard to suck. If you go bigger on the outlet of your pump, then to get the full benifit, then you need to increase the inlet size.
Any (electric or mechanical)fuel pump for a engine, needs a larger suction line than discharge, no exceptions. Do guys do it differently, yes. Does it make it right NO!
The short distant from the engine mounted fuel pump to the carbs is very short, so 5/16" line will carry the load in most cases. If it's not big enough, then the suction side isn't big enough either. Fuel delivery is my specialty, for a long time now.
