RE: Windshield washerpump ?
On a related note: I'm planning to put together a nice rollaround fueling/starting station over the winter, and I'd like to have it offer two or three different glow fuels (e.g., 2S/4S/Heli), selectable by a valve connecting the jugs to the pump. But where to get the valve?
There are "Y" valves meant for garden hoses, but of course those are enormous compared to the size of model fuel tubing. There are also valves meant for natural gas, but those are simple on/off valves that would have to be ganged to a manifold, making the installation both cumbersome and big, and they still need a lot of size adaptation. Even with the necessary adapters, the volume of fuel left in the valve cavities after a fuel switch would be enough to mix the fuels significantly.
There are various valves meant for actual fuel tank selection on the auto market, but those are big-buck items.
Finally, there are some valves on industrial websites that look attractive, but they're invariably priced as "Call For Quote", which is marketing talk for "How many boxcar loads do you want?"
Does anyone know of a source that will work?
