I have a 1989 Ford 7710 II. It was running great until I ran all of the fuel out of the upper tank and only had fuel in the lower tank. I did some research and thought that my fuel lift pump must not working. Well, after looking at my repair manual, it shows a completely different type of injector pump than what is on my tractor. 
... So after more researching, it appears that what is on my tractor is a rotary injector pump. I attached a picture so hopefully someone could confirm.
Does a rotary injector pump use a lift pump like an inline injector pump? If so, where is it located and can it be rebuilt? I'm new to this type of system so any help is greatly appreciated!
Thanks,
Doug
