Check out the fuel pumps at Summit Racing and other hot rod web sites. The pumps made for high horsepower race engine are cheap and readily available. Make your own "dipstick", with a screened inlet, easy peasy.
The thing I never liked about filling with jugs from up top, besides the dripping spouts, lifting, etc., is that when I was up there.....I couldn't see the site gauges in the wing tanks. So, I'd either have to jump and down and check, or, and this happened more often then not, in an effort to max out my capacity, add just a little bit more and sure as heck, dump fuel all over the wing.
Pumping is the lazy man's way to re-fuel. If there is a static hazard....I have not found it yet,(or it hasn't found me) and it's been 24 years not 20 of me doing it this way, almost all my re-fueling is done this way, 200 hours a year, 4 gallons an hour. My ultralight XC background got me thinking of this method, (landing somewhere, not an airport, before bush bags and no room for jugs, scrounge up a borrowed jug to get gas, but the spout drips or is missing, pumping makes a spout of any sort immaterial) when I got into "real" airplanes it was a natural for me to continue to handle my own re-fueling needs, using mo gas exclusively.
