i am going to add an electric pump on the frame rail in a couple weeks. I have some questions. Do I just use a tubing cutter and cut a section out of the fuel line? If so, do I just slip the hose over the line and tighten the hose clamp? What size hose? Where to pull power from so it is off when ignition is off? The mechanical pump has 1300 miles on it. Can I leave it on, in line or have to at least disconnect the hoses? Is the Holly Red good and if so which one? Is there a better one for about the same price?
