Upgrade fuel system

Dear TM, As far as the sending unit is concerned you can go to ebay (oh the horror) and search "mopar sending unit". I use a high volume mechanical pump on my 383 with a 750 double pumper with no concerns what so ever other than I had to add a pressure regulator set at 6-7 PSI. But then you got to consider that if you're only going to a mild build up do you even need to spend the money for a 3/8" fuel system. I say no, not required and stick with the 5/16" but that's just my opinion.
