Hi Joey! Here's an answer from Steve Ells:


There are two pumps in each main tank in a 310R. One is the auxiliary pump--it is turned on to prime the engine for starting or to provide fuel pressure if the engine-driven fuel pump fails. It's turned on from the cockpit.
The second pump is called the transfer pump. It's located on the aft side of the main fuel tank bulkhead. This pump is ON whenever the master switch is on. It is there to transfer fuel from the nose section of the main tank to the center section. This pump insures that fuel will be available when the fuel quantity is low and during steep descents.
You don't want to pull the CB while operating the airplane, but it's OK to pull it (and flag it to make sure it's reset before flying) during maintenance or avionics work.
Does that answer your question?
Steve

my question regards the fuel management on a 310 R with mains and auxiliary tanks. is there a fuel transfer pump on board, or do you simply cross feed the fuel? the seller of the aircraft told us to pull the breaker on the landing gear to keep the auxiliary fuel pump from running. my avionics guy thinks the the motor for the landing lights simply run on and that is the reason to pull the breaker.

does anyone have any advice for me?
