My compressor always has air in the tank and set
to 110 PSI
I have a inline gate valve so I can close the air line off so tank
stays full when not in use.
If I had to turn it on just to pump a bike tire I would not bother
with it a floor pump is faster.
With that said here is what I did to make this work on my Presta
Harbor Freight sells these I modified the one I
had already it works good so
I may get the one with the dial next time I go to Harbor Freight,
but the dial is really not needed
since I set my compressor to 110PSI
that's were I run my tires anyways.
