No problem with removing it. Connect your vacuum advance to the proper port on the carb, connect the vacuum line to the trans to a port on the Vacuum Tree

Mine is an automatic and there was no connection from the Atascadero to the transmission. 2 different post on the cab, one manifold and the other ported and the other end to the distributor.
There is a vacuum line that goes to the transmission but not from this valve. A hose goes straight from a port in the intake manifold to the transmission.

As long as the manifold vacuum tree is connected to the transmission modulator valve and vac pot connected to the correct carb port the rest can be pulled

my trans is a TH350

I think I’ll keep it. In a box for the next owner. Along with the fuel cannister…

Keep the canister hooked up to control fuel smell. It also adds a little pressure on the vapor line. I’ve had fuel come running out on a steep hill when the nose was pointed down hill when parked with the canister removed. Its easy enough to put a T on the PCV Line or get a PCV with 2 ports to burn up vapor
