The original coolant hoses installed by the Fantasy Air factory on our less than
4 year old Allegro 2000 w/ 912UL showed signs of age cracking during our annual
inspection in May of this year. They were made from pretty thin stuff so we
replaced them all with Aeroquip hoses which appear to be very strong, multiple
ply, and are much thicker. They are also much more expensive but should last
a very long time. I don't have the product number in front of me but think it
was Aeroquip FC252.

Thilo:
How old was the hose? If there was no restriction in the flow path
(blockage, or partial blockage) it sounds like the hose was defective, or if
the hose had age on it, it had become brittle and vibration finally caused
it to rupture, but your guess is as good, if not better than mine.

I am not entirely sure. what caused the hose to burst. It was the hose from
the water rad to an aluminum tube and from there from another hose to the
pump. The hose did burst lengthwise over a length of approx 12".
It looked like it started at the aluminum tubing, so I suspect the edge of
the aluminum tube was too sharp (although I couldn't feel any burrs). The
hose was not near the exhaust or any other hot items.
