And teflon tape is more likely to plug stuff up if a little tiny piece of it should somehow end up traveling thru the system, pain in the arse to get out of jets and idle cicuits, etc. Paste is much much better. One of the many jobs I do is replace fuel hoses and pump handles for several local convienance/gas stations and the new pump handles/breakaway fittings/hoses all come with big yellow tags warning NOT to use teflon tape for the same reason, to prevent plugging up some poor saps fuel system with chunks of that crap.
