Are the two lines on my driver side 79 regal my supply and return? What i believe to be the return is 1/4 and routes from passanger side and runs a bit longer than the supply which looks to be 3/8. Ive had it set up like this on the pump but the carb is getting no gass. Pump ois good and carb as well i bottled tested the system and almost got car to stay running.
