Hi, First time poster here, recently purchased 1957 CJ5, dealing with fuel issues. I would like to change from the dual action fuel pump to the single action pump. My jeep uses electric wipers anyway. I am wondering if this is OK to do. What do I do with the vacuum line going from the crankcase vent up to the intake manifold via the fuel pump? Do I just change the plumbing to bypass the fuel pump? Or is there more to this? Thanks, Tom from Mass.
