[TR] Fuel percolation

[kinderlehrer at comcast.net]

OK, at the risk of being vaporized myself by the return flames, I'll throw out a thought I just had (it happens) for consideration of the group .... 



What would happen if under those conditions, one were to spray the fuel lines, possibly the float bowls, with a product like Dust Off? It's basically compressed air, but gets very cold when used.  I'm guessing it's a bad idea because of the temperature differentials and what it might do to the metal parts subjected to such extremes, but I'm just guessing.

I've seen percolation on several cars over the last year.  I agree with 
Randall, I think it is a result of the fuel they are selling now; the 
addition of the ethanol lowers the boiling point of the fuel.  I've seen 
fuel literally boiling in the jets of an SU H6 equipped TR4 recently.  This 
tends to happen after the car sits for about 15 to 20 minutes after shutdown 
and the heat has enough time to "soak" the carb bowls and jets.  The TR4 in 
question did have a heat shield and we had rerouted the fuel line away from 
heat sources.  We were also running a low pressure electric fuel pump in the........
