ewingr, That stuff looks like it will do the job.. Seems kinda pricey tho.

Ives' comment gave me an idea. Lay hands on a non-contact temperature measurer. One of those point-the-laser-spot-read- the-temp guns. Warm up your ride. Idle around your street, parade wise, for 10-15 minutes. Then dart underneath with the temp gun and scan the entire fuel line.. This would be VERY telling!

Remember the temp gun sees the light of warm objects so as you use it imagine everything giving off light that signifies it's temp, and use the gun appropriately. Another words don't point it at a fuel line that has the exhaust pipe behind it as the light from the exhaust line will trump the fuel line and your reading WILL NOT be telling you the temp of the fuel line.

You may find that you only have a one or two foot section of fuel line that needs insulation or shielding.

Between the fuel pump and the carb?? Yeah, you can get some boiling fuel but it is a lot less likely to be the problem.
