Need some help here...We have a KF member with a Henry J with a bad fuel pump. He is in poor health and can not replace it himself. Can some one provide some off the shelf fuel pump part numbers/sources that will work for a HJ? I am not sure if he has a 4 or 6 and whether it needs to be a single action or double. I plan to have our local club replace it and get him back on the road. Thanks in advance for your help.
