The original method is to use the BVM “Air Fill Chuck”
that is safety wire retained to an air pump as shown
here. You must thread the knurled end of the chuck
onto the Air Fill Valve in the model. Note that the safety wire wrap is
covered with electrical tape.

An alternate and faster method to inject air into the
model’s storage tank (s) is to use a 2nd Air
Fill Valve (BVM#5758) (threaded into and stays with the
Air Fill Chuck) with a piece of BVM Heavy Duty Air
Line (a 3-5” piece) fitted to the Air Fill Valve on the
pump side. |

Use a razor to put a slight angle on the open end of
the airline to help guide it into the Air Fill Valve in
your model. Because of the slight variations of the
tubing O.D. and the Air Fill Valve I.D., the tubing may
be a loose fit.

To adjust the O.D. end of the tubing, push it onto a
2mm diameter steel shaft such as this Wiha 261 x 40
Phillips Driver, then heat it with a heat gun.

After it cools the tubing should fit snugly into the
model’s Air Fill Valve. Our tests showed that the
“perfect fit” withstood warm and cool ambient
temperatures. |
