Need to know what type of fuel line can i run from petcock to carb line? My 85 Honda Magna came from last owner w/ clear vinyl tube that toasted and spilled gas in my garage--scary..normal rubber fuel line too stiff to bend into the impossible S shape from petcock to carb line--what else can i use that won´t toast and melt eventually--that is flexible heat proof and appropriate? only need 4 inches!!
