I have inherited this Maxxis Air Elite Floor Pump. It is working well except for a critical piece as you can see in the attached image.
I have an existing pump so would like to set this one up to use exclusively for schrader valves, however I'm struggling to find any information online. Any advice where I can get a generic part or adapter?
The LBS was no help, and I'm not sure how to match the threads from parts I see online. Would hate to throw it away.
