The Finescale GWR48XX has a vertical action hand pump--in the side tank as there is no tender. It works very well.
Frankly, I have had hardly any problems with tender hand pumps or the check valves (balls) in 1/32 up to 1/16 scale locos. That, of course, is because I didn't build them!! I only recall one incident where I had to take one apart. In one other case some air pressure to the outlet piping solved the problem. The air pressure to the intake or oulet will often free up those obstinate little balls. Geoff. > >You could make one that pumps up and down. I recall seeing one in a past >issue of Garden Rail.
