i replaced the stock 4 barrel carb with an Edelbrock 750 vacuum secondary carb and now the fuel line from the fuel pump to the carb collapses. how do i repair this malfunction?
Sounds like your new Edelbrock sucks to hard. The fuel line can’t deliver that much fuel that fast. So you need to either get a larger diameter fuel line, preferably one built for high suction or go with a metal line.
