I can't speak as to the Black Silicone looking thing he used on the seals.
But I do believe it said it was ok for gas. Not sure.
Gravity Valves are where?
On top of each tank in the wheel wells.
Vapor Recovery valve is on the left, right front or behind the air filter?
What should I do with it once I locate it?
In front of the air filter on the other side of the firewall. You should be
able to hear it click each time the throttle is opened when the engine is
running.
I never have heard any pressure release sounds coming from the gas tank cap
and this is my second van, so what is missing?
Something is leaking somewhere. Just think later cars will generate a fault
code when the tank can't hold vapor pressure.
Thanks,
Robert

Silicon and gasoline. What was someone thinking. Most say on the tube not
for use with gasoline or on head gaskets. It could just be a loose hose or
one of the gravity valves on top of the expansion tanks. Also check the
operation of the vapor recovery valve near the air filter. If all is well
whenever you open the cap for filling you should hear some pressure
escaping. After repairs the tank and vent system can be charged to 2-3 psi
to make sure the vapors are kept in.

A year ago my mechanic and I removed my new gas tank and installed the
crossover pipe and a seal kit with all the rubber grommets and clamps. He
used some special RTV silicone on all the rubber grommets before installing
it.
Now it's a year later and the smell of gas permeates outside the vehicle
when I fill up. I have no idea what to do.
I am at my wits end at this point.
Either a hose is damaged, or a seal must have blown ( hard to believe with
the new rubber and RTV silicone though).
Does anyone have any advice?
Thanks,
Robert
