Well, it wasn't the fuel pump that stopped working on the '40. The tank lining wasn't done correctly which led it to flaked off and clog everything.
The lining company made good on their work, but the carbs are completley packed full of crap. I did managed to get it running but it's not right. I think I am going to have to pull the carbs back off for the third time an rebuild them.
I did find a decent article on rebuilding the Rochester B carb over at bangshift.com If anyone reading this has some good tips, feel free to hit me up.
