I would like to add something current to the subject of Fuel Boost pump overhaul. I highly recommend Aeromotors LLC in Wisconsin. after studying these comments I sent my boost pump in from Florida (a Mooney Ovation). before sending I called in and was given simple instructions on what to do. Following those instructions my pump arrived at their facility on a Tuesday February 8th ...to my pleasant surprise it was back on my doorstep Friday February 11th, back in the plane and running the same day! you can't get any better than that! Thanks to Aeromotors we are back up and running for our trip on February 25th thru March 1st. We were pretty sure that trip would have to be cancelled due to the Boost pump. Big thanks to Aeromotors Theresa, and the staff at their facility. Also thanks to all who posted on this subject...Mooneyspace.com has been a wealth of information for mooney fliers.
