Today I went shopping for new oil cooler hoses.
I decided to route these lines from the oil cooler over to the frame, then
follow the frame forward to near the radiator. I'm using right angle
fittings on both ends.
The first place only had a nitrile hydraulic hose. It looked like pretty
good as it had two steel braids where our originals only had one. I noticed
it was rated for 212 degrees maximum, so I rejected it. The guy sent me
across town to an industrial hose supply house.
Here they first tried to sell me a similar hose. I mentioned the aircraft
uses stainless over teflon hose. They had it available rated from -100 to
+450 degrees, rated for 2,000 psi working. My new Parker teflon hoses and
fittings are on order.
I also had them put on a fire sleeve cover. This provides added protection
from damage and more important allows any leak to drip out the end rather
than squirt out onto the exhaust manifold.
The best news is the price. First place wanted $55 for the rubber hose
without fire sleeve .
Teflon hose will be about $70 with fire sleeves.
I tried three auto parts places before finding one who could order in a 25'
roll of steel tubing to make new transmission cooler lines.
The young counter guys never heard of tubing in rolls. The older ones
laughed and said nobody ever does that anymore.
Tsk. Tsk. What is this country coming to?
