Cut a valve/pump mounting plate out of scrap
ply, approximately 2 inches wide by 6 inches
long.
Mount components as shown in the photo.
Make a mirror image arrangement for the other
side.
Using velcro, temporarily position plates in the
wheel bay, making sure that there is adequate
clearance when the main retracts. Make sure
the main tank will fit in its bay.
You may hook up the fuel and gas lines to the
engine at this time. Insert intakes temporarily
to check for adequate clearance of the various
lines. Don’t forget the manual shut-off valve.
Fuel System
In the prototype, two additional tanks were
positioned in the area behind the main tanks to
increase overall fuel capacity by another 25
ounces. Production kits may have a different
tank configuration, but if not, the auxiliary
tanks may be obtained from JetTech. Make
sure to order them without the clunk opening
cut out ... you will do this yourself once the
tanks are in.
To install the aux tanks, you will slide them up
through the intake opening on the underside of
the aircraft. They may need to be extended
slightly to provide clearance. The rear hatch lid
may also need trimming.
