Hey all! I recently got a 1960 Willy’s CJ5. The previous owner put in an electric fuel pump. I need to replace it, however, since it’s acting up. I can’t tell what type I need to put on. Got an F Head 4 cylinder. Specifically curious about the flow of fuel. Do I get a 20 gph, 30 gph, or 38 gph. I don’t want to over do it, but not sure what to get. Attached a picture. Any suggestions are appreciated. Thank you!
