After changing out all the rubber lines on my MT372D I sprung a leak on a steel one. The steel line coming from the power block{left side of seat}, to front of the oil filter housing. At that juncture, which appears to be a banjo fitting, is were the leak occured. It's hard to tell if I have a cracked housing or o-ring failed. Worst case scenario, does anyone know where I can find a new or salvage part?
