This is a late response to your request for assistance with this
installation.
I scrapped the stiff, difficult-to-work-with hose furnished with
the kit and substituted high quality stainless-braided teflon hose and
stainless fittings. They're flexible, look terrific and will give superior
service in the long run. The drawbacks are that they do cost (approximately
$ 400. for the complete installation) and the fittings have to be crimped by
a local shop, after you determine each required length. The low pressure
hose from the bulkhead to the inboard port on the main gear cylinder is
short, but no problem with these hoses...they're flexible. I used
Parker-Hannifin HT04-NJ stainless fittings throughout.
Here also is a design improvement that I should have submitted
long ago...rather than route the high pressure for the gear cylinder and
inner gear door actuator from a "T" fitting (middle fitting in the
bulkhead), I simply used a 45 degree fitting to route high pressure directly
to the gear cylinder (outboard port), where I used a pipe "T" and ran a flex
line from it (in a loop) to the inner gear door actuator. This makes for a
very neat installation and eliminates the tire clearance problem caused by a
bulkhead "T".
