I've used a 0.36 ci pump on the loader I've made for the B7000 I used to own. It worked just perfectly. Just the right speed and it would even allow me to do 2 functions at the same time. But then again, it all depends on the size of your cylinders.
The lift cylinders if I remember right were around 1.5" bore and the curl had around 2 1/4" bore.
