Trying to map out my fuel system. I think I know what will work after reading multiple threads on the subject. My car is a 73, I will be using a tank from Spectra. I know from the factory that I have 2 fuel lines running up the passenger side of the car, a 3/8 supply and a 5/16 return. On the driver side there is a 5/16 vent line. I plan to use the vette filter (wix 33737) as my inline filter and use the return line coming off of the filter as my return going back to the tank. So this should eliminate one of the lines going to the front. I'm thinking that the stock 3/8 line should be sufficient.
