I bought my 4th BMW in as many decades earlier this year, '95 R1100RS with a couple issues, preceded by (2) /6s and a short lived K1100... with my work schedule I entrusted a guy I've known nearly 30 years to service the bike, replace the tires and all the fuel line. I had a great 70 mile ride home, topped off the tank 30 miles shy, on arrival I found fuel leaking/pouring out of the drain line (ruptured inside the tank)- apparently my acquaintance translated "all the fuel line" to "all the fuel line that's easy to get to"... I have no plan to trust this guy again. Nearby dealers out of stock... what I ordered was advertised as SAE30R10 but has no such marking, despite assurances I am not inclined to install it inside my tank. Any thoughts or suggestions? Thanks
