I would buy another fuel cage since its a pain to drill it. Also its not a 3/8 drill bit that is to small I used 1/2 for my -6 fitting. I got silicone from lowes and it exploded so I had to use a screw driver and scrape it out the tube. If I was running a dual pump I would buy the cnc machines one you just pull out one out and drop new on in and wire up the connectors.
