I have gotten to the point of driving the motorhome. I had the quadrajet rebuilt and I use an electric fuel pump. When I went through the fuel supply system and replaced all the hoses I also added a connection for fuel return to the tank. Before I drive extensively I would like to install a pressure regulator that allows for any excess fuel pressure to bleed off so as not to flood the carb and or allow any raw fuel into the engine. I have read about engine failure from excessive electric fuel pump pressure destroying carbuerated engines. Now for the questions. What pressure should I set the regulator at so as to not over power the carb? Is there a good way to set this up to help avoid the dreaded summertime vapor lock. Thank you for any and all suggestions. I really appreciate the help and advice.
