I do not have and A12 car but I run a 440 6bbl. The car still has the original 5/16 fuel line and it needs replaced so I figure now is the time to swap it to 3/8. The question comes at tying the 3/8 line into the factory style carb lines which were all 5/16 as far as I know. How did ma mopar handle the transition? The brass blocks on the carb lines are threaded for the 5/16 line.
