I had a Dukes Aux fuel pump 4140 start weeping near the bottom of the unit. The folks (Bob and Oley) at Aeromotors LLC Browntown, WI had a replacement sitting on the shelf. So, after a little road trip, the plane was back flying in a day. They were extra friendly spending quite a bit of time showing the overhaul process and facilities. Highly recommend them if you should find a need for a replacement.
