purpose of coil spring aound fuel line under tank?

[fjrpierre]

Is that just to prevent kinking or is it heat protection?

Hello,  The fuel line was cracked and needed to be replaced on my 86.  It had a very stiff molded (s?)  rubber piece on in.  I replaced the line with the correct size hose, cut to the same length as the one on it.  I could not get the molded piece onto the new hose, so I ignored it.  The bike ran for about half a mile and quit.  The fuel line has kinked badly.  I think that the heat of the engine softened the hose and allowed it to kink. 
     So in my opinion your spring is definitely to stop the kinking of the short hose, and may play a part as a heat shield also.  But I expect other members to post how wrong I am.

Since metal absorbs head and since i also use springs in order to bend copper tubing without kinking it then i'm gonna vote for this part to have "anti-kinking" properties rather than any type of heat shielding   


KOokaloo!

I would think it is on there to protect the line from permature ware.

I think it focuses the Earth's magnetic lines of flux in the direction of the fuel flow to increase power.
