Whoa! Unbelievable... I see what you are saying. What I'd do is take off the
hose and drive it down to a local hydraulic hose shop and have them fit you
a new hose. Probably cost you $100 to do this.

However, where is the leak at? The fitting? If at the fitting, then change
the oring... there is an oring there. If it is positively the hose, then
take it down to have them rebuilt that hose.

I think somewhere the price for the hose and the price for a new pump have
become confused.
Can you be specific about which sellers list the hose for $1299+?
None of the on-line parts sellers I use have the pressure hose listed for
more than $110 or so.

I'm not a very good DIY mechanic, but I once replaced one on my previous
Land Rover Discovery. A emergency assistance mechanic (Dutch AA)
diagnosed the problem, one of the high pressure hoses had rubbed against
the radiator for 11 years and had started leaking eventually. He told me
having it repaired by the dealer was going to be expensive, but it was
easy to do it myself.

He sent me to a truck hydraulics repair center where they put a new hose
on the old 'connectors' (not the proper word), and I just screwed the
new hose back in place, added new fluid moved the wheel back and forth
for ages until it stopped making noises and all wwas well after that.
Cost me something like 30 EURO's for the new hose.

I expect the procedure won't be much different for other cars.
