Leather Washer

Q -Kindly recommend some substance which can be applied to the leather washer of the pump so as not to allow the air to filter through and thus cause loss of time. I have been told to oil the leather, but the oil, will, after a time, be forced through the leather.

A little neatsfoot oil or castor oil applied to the leather washer of the pump should remedy the trouble you speak of. If this does not do it, it would seem advisable to install a new washer.
