Got a White 2-105 tractor. had it about a month. Using it Monday and it ran out of fuel in lower tank that is in front of the right axle housing. After inspecting the system set up, I turned on the upper tank and let that fuel in the lower tank. It took a lot of priming of the pump, but finally got it started. Now, it is hard to start every time. Is this the way all the 1955 Olivers and White 2-105's were plumbed, to pull of each tank individually and you have to switch the tanks back and forth? Has anyone ever put an electric pump between the tank and the pump on the engine? Just trying to get educated on the unit. I have a parts manual and owners manual ordered. Nice tractor and I enjoy using it, what little I have; just a few squirelly things happening.
