Since my carburetor had rust in it and the tank is a mess, I have decided to buy a new SS tank from Mike and replace the fuel lines from the tank to the engine. They are easy to get at and not made of anything exotic. I have a double flare and tube bender so with all new parts, I hope to be ahead of the game. I will most likely replace the still original rubber fuel line that goes from the frame to the engine with conventional rubber fuel line. I also intend to use high pressure fuel line designed for fuel injection and high pressure clamps. Yes, it costs more but I hope to only do this one time.
I will let you know how it goes. I just can't see taking the time to rebuild the carburetor (I already did) and then just pump rust into it again. I am undecided as to whether I will put another filter at the tank. I think that using a new tank will eliminate that issue.
