My actual airtex 8012s electric fuel pump is barely 3 psi at the carbs. I found a stock spare one on my garage and would like to swap as i believe the metal filter could be clogged inside. During the process i would also like to replace the fuel lines that go in and out of the pump with new rubber hoses. I believe these lines are 5/16". Am i correct?

Flow line is yes, return is smaller, I think 3/16".
