John B,
Sorry, but I want to put =9Csloop=9D in front of your name.
Yeah, you have to have a pressure indicator in the cockpit, otherwise
you don=99t know when to unload the compressor. One was installed
when I acquired my Yak.
I=99ll check this weekend to see where the tap off is. I=99m
sure your Yak has a ground air-charge fitting just behind the trailing
edge of the left wing root. I think the tap off is within the fuselage
on that line but will verify for you. I have had to replace the 1,000
psi gauge required several times. So if you are going to fit one, get a
few spares and if you have a system air leak check there first.

Royden-
The airplane already has one of these installed. So, I don't have an
air pressure indicator. How does one install one?

An alternative to cooling is to stop it getting hot in the first place.
Install an unloader. Kimball sell a kit. It is a valve that is
switchable from the cockpit that vents the out going compressed air line
to atmosphere. THe compressor will not heat up while it is nothing to
compress. Venting to atmosphere probably save a bit of power too. I
start the engine with compressor on and by the end of run up the
pressure in the receiver is up to operating pressure, then flick the
switch to vent to atmosphere for the flight.

Does a cooling shroud for the air compressor exist for the M14P?
Perhaps something similar is available from the CJ operators? I'm a new
operator of a Yak 55 in Arizona, and I'm wondering if improved cooling
would be a good idea for our high summer temperatures.
Thank you!
