Fuel lines and fuel pump have been changed. This is not my car but my husbands and I really want to help. Any suggestions. Originally it ran fine when we got it. Then it started stalling when idling for a period of time. He called it vapor lock. If you pour gas into the carburetor it will start but not stay running. Needless, to say it's very frustrating for him because he can't take it out. It is a beautiful car but we can't really enjoy it. Any input is appreciate it.
