My fuel pump died this weekend, lucky for me I was only four miles from my father-inlaws farm. He towed me into his shop, wow was that fun with 40 inch tires and no power steering or brakes. My question is, I have a early low pressure tank mounted fuel pump (13-15 psi). Can I leave the old pump in the tank and just run a inline unit, or do I have to remove the old one first?
