Update: Overheating Fuel Tank.

["therealdmcvegas" <DMCVegas@xxxx>]

Took my car back out again today, and recreated the same 
problem. This time, I had filled up the tank, and got the same 
problem. So filling the tank with cool fuel fresh from the pump 
doesn't solve the issue. Now, I've had this same problem since 
before I installed the spring inside of the fuel pump pick-up 
hose. The only difference is that since installing the spring, I'm 
able to maintain accelleration. Although, I am al for excluding 
both the spring, and the pick up hose all together to avoid these 
potential problems.

However, here is an interesting fact. I disconnected the vacuum 
hose from between the carbon canister, and the intake manifold. 
I clamped the manifold hose, and then connected a vacuum 
hose to the canister. Engine started, and idled fine. When I 
applied the vacuum, nothing happened. Until I increased 
pressure up to 12 PSI. Once this happened, the engine flooded 
out from the vapor pressure from the gas tank!. After this, I was 
able to get the same results @ about 5-6 PSI. Once I applied the 
vacuum, it would slowly decrease until it reached 3 PSI. Are 
these normal pressures for the diaphram inside to activate at? It 
seems to me that the diaphram is malfunctioning, and is the 
cause of the swelling of my fuel tank. If it was properly "draining" 
the gas vapors out, I don't believe that the motor would have 
flooded. If nothing else, I need to replace both the canister, and 
the hose(s).

Can excess pressure in the tank cause a noisy pump? My gut 
feeling is that it's what's responsable for my fuel vapors inside of 
my passenger compartment. Although I still intend to shield the 
tank from the water pipes below.

Thank you for all of the input so far both on, and off the list. I do 
appriciate it!
