Fuel expension tank delete?

[Charley]

I'm in the middle of a rear end refresh right now and everything is out
but the gas tank (witch will come out when I will have the time and some
help)

Anyone ever deleted the expansion tank? Along with everything related to it?
(tank itself + all hose +charcoal canister...)

I would like to connect the hose from the tank directly to the check valve
that is usually after the charcoal canister...

When I had my 318is I bypassed the charcoal canister only and left everything else there and it worked flawlessly. Now if I remove the
expension tank as well will it still work?

And no I don't care about emissions.

It is possible to delete the charcoal cannister and expansion tank. But if you do so you need to provide a means of venting the tank directly to the atmosphere. Doing so has the possibility of a fuel spill if you fill the tank to the top with cold gas and allow the car to sit in the sun on a hot day.

If you delete the charcoal cannister, plug the hose from the tank and the valve. Do not connect the hose directly to the valve as that could result in raw fuel being drawn into the intake.

A better solution on a street car is to remove just the charcoal cannister, plug those, and vent the expansion tank.

I didn't thought that raw fuel could reach that valve... now I know.

And I didn't thought of that either...That what I'm going to do.

If can't, if the expansion tank is in place. But if you eliminate the expansion tank and plug those hoses there is the possibility of sucking fuel into the intake.
