Cannot share a ton of information right now, but this should officially "launch" in the very near future... Two pumps are better than three, and we'll prove it! The 1500 refers to the number of horses that can drink from this beast, and as always it will come with OEM-level fitment and finish. The first kits will ship with a bulletproof electrical installation kit that is as "smart" as it is tough as well. The second round will include all hard/soft lines and fittings needed to make a complete fuel system. The third round... Well, I can't talk about that round yet, but it will be even better yet! A couple preliminary answers: 1) Yes, the OEM level sender will mount to this unit (not shown in pictures) 2) Yes, these pumps are quieter and more efficient than the Walbro units that are so abundant 3) Yes, we have completely sealed the hat so that no fumes/odors get into the car
