Can a manual petcock be used? Yes it can if you block the vacuum line. BUT, The purpose of the vacuum one is that when the engine stalls, IE; tip-over, accident the fuel gets stopped from running into the carbs, so there is a potential fire if you change to a manual in cases like that as the fuel pump runs continuously with the switch on, the vacuum petcock opens when there is vacuum from the engine running.
The rebuild kits from K&L were discontinued last year. There might be some across the pond, but limited.
There is a post on an electric petcock being used in replacement.
