Re: rubber vs steel fuel lines

With today's fuel,rubber(neoprene) lines degrade inside,very quickly. The new fuel lines are neoprene outside,but have a plastic lining inside,that is not affected by the ethanol/additives in the fuel.
If you use the new line,as I have,it should be OK. However,as a precaution,use quality clamps,and fittings,and put loop-clamps about every 3 ft.,on long runs,to prevent sagging. Also,make sure they are protected from heat sources.
I run steel line up to the carb,on the engine,but all the rest is the new type neoprene line.
