Fuel pump issue
I have a 72 blazer, when I bought it someone put an electric fuel pump, it went out so I replaced it with a mechanical pump. It has a return port and my blazer doesn't have a return line. So my question 🤔 can I just plug it or should I replace it with a pump with no return???. Thank you all in advance.

Re: Fuel pump issue
IIRC, all 1/2 ton 72s had a fuel return system.. Maybe some previous owner removed the system.. To answer the first part of your question -- No, you should not block the return at the pump. The correct solution is to install the missing parts of the system.. The return's main purpose is to prevent vapor lock...
