Walt,
Well, I am not sure about a Webber DGV, however I had this problem when I
first got
my B with HIF style SU's. The problem was that the needles in the carbs
were sticking
open. So, the carbs were never building up any pressure to shut the fuel
pump off. :(
The fuel would fill the carbs then escape into the fuel vapor removal
system as you are describing.
That thing in your trunk is supposed to be for collecting gasoline vapor
that your car does not
burn. Supposedly, it collects the vapor allows it to flow back into the
gas tank.
And no it should not leak. First of all, if the car is working properly
there should be little or no
fuel being recirculated in this manner. Secondly, if fuel is being
recirculated and all of the hoses
are in tact the fuel should end up back in the tank not in the trunk. :)
If all of the hoses are installed correctly, I believe that the only way
that fuel can get back into that system
as you have described is through your carb. I would check your carb float
and make sure nothing is sticking open.
However, when your Webber was installed it is possible that this
recirculation system was altered to bypass the
carb all together. Their should be some hoses that run from the general
location of your carb over to the right corner
of the engine compartment (possibly to a charcoal canister), they then
connect to steel (or maybe copper) tubes
which run under the car back to that thing in the trunk. If these hoses
are bypassing the carb, it might be your
pressure regulator or a simple blocked fuel line.
There are some places to start looking
Hope this helps a little.
