My hoses are leaking badly, 1-pint every 2-3 days! Smokes like crazy when hot. Mechanic said the high pressure hose was leaking and the return hose was swollen and leaking at the fittings. I've had the hoses running to the cooler spliced with metal tubes. Can I do the same to the high pressure hose? Or is the pressure too high? Shop said the hose alone was like $260! Can these be fabbed up by an AC hose shop or similar?
