Yes leave the tack drive and lower part attached and block off where the pump attaches ...my motor with the car carb and everything needed and electric pump and manual switch on it to allow me turn off pump and drain the carb dry while it’s running after a ride ...one thing I found out about weber carbs and DFT clones is they need the electric fuel shut off solenoid or they will leak after running ...till I get another one this is how I keep that from happening ...work great ...and the carb being so tall above motor the electric pump puts gas right there to the carb before I hit the starter and it fires up instantly with the machanical pump I’d have to crank it awhile before it would fire up from gas trying to go back towards the tank while sitting
