Re: Update: Overheating Fuel Tank.

>From your description I am not sure what you are doing but if you are 
having pressure problems with the fuel system reconnect the vacuum 
hoses and try running the motor with the fuel cap loose (put it on 1/2 
way) If for some reason the tank is running at a negative pressure 
then the fuel pump will have a hard time trying to get the fuel out of 
the tank against the vacuum. On the other hand if the tank is 
"swelling up" then you have a positive pressure problem. Again 
loosening the fuel cap should temporaraly "fix" this. If loosening the 
cap helps then you have to go over the vapor recovery system to see 
what is causing the problem. The fuel system for the engine doesn't 
work if there is any vapor in it, it is a totaly positive pressure, 
liquid system. The only place the vapors go is the vapor recovery 
system. If the fuel tank is at a negative pressure that would 
aggravate any tendency to cavitation before the fuel pump i.e. in the 
suction pick-up hose. Unless you are in extremly hot conditions if 
everything is functioning correctly you don't need any modifacations 
or insulation to the fuel tank.
