Good question.  The aluminum tubing sort of "floats", and is

connected

to the filler neck and the fixed radiators by short sections of

hose.

It is also connected to the pump inlet/outlet by sections of hose.

The

filler neck and overflow are bolted to the firewall, but the

aluminum

tubing is not.  The tubing is clamped together in two places with

the

back part of the clamp a wood block (painted silver) which rests

against

the firewall, but is not bolted to the firewall.  You can see one

of the

clamps in the photo of the installed bottle, and the other in the
attached pic of the left side of the installation.  Look just

below the

oil filter (one of dual filters).

This photo also shows the oil plumbing to the wing root cooler,

and the

hose to the heater.

Beatiful fabrication Al. You are going to Clamp all those loose lines

before

you fly though aren't you? That braided hose would saw away at the

mount

otherwise.

Oh, yeah.  Haven't begun with the wire ties/adel clamps yet; that comes
last when all the tubes and wires are in place.
