Does anyone incorporate the Great Planes or Dubro Fueler Valve into their planes? If so do they function okay for you? I've got'em on a couple of my planes and both exhibit the tendency for the fuel valve to stick inward once the fuler probe is removed. Anyone else experienced this same issue? Anyone figure out a way to solve the problem? I've replaced them, but the replacements work okay part of the season and then do the same thng.

I've found the fuel "dots" to work the best. They are just a line plug on a 3rd line that goes to the fuel tank. Simple and effective.

I use a plastic tee on the fule line for the motor then plug the open line with a piece of plastic rod just large enough for a press fit. Close the carb before fueling or defuling and works just fine for me. Almost no cost at all. Air line tees work great and for larger fuel tubing for the larger motors I get the tee at the auto parts place.

I have several, two of which do exactly as you say. The others have never failed (except an O-ring on my high-mileage Corsair.)

I think the sticking comes from a stackup of manufacturing tolerances, since not all of mine do it. Might as well replace 'em and see if the next one's any better. I actually have one that's been that way for about 8 years, never had to replace the O-ring or anything, just fiddle with it until the little center thing finds its seat, and fly.

I'm ordering one of the DuBro 996 asap, different configuration. No special nipple on the end of your pump line. Pull out the fueler nipple to fuel, push it back in & cap it (to keep dirt out) to run. This one will go under the firewall of my Cap 232. If I like it, there will be no more of the other type for me.

Good luck,

I have Dudro fueling valves and try to build them in always, very good and trouble free. Remote glows are a good idea as well as the quick charging socket and switch.

I have not had much luck with fuelers, Dubro, chinese copy of a dubro or the Robart.

All I do now is run the fuel line to the engine out of the fuselage, join it with a short length of brass tube, then back into the fuselage to the filter & carb. If it's a scale model or something pretty & hide the tube behind a simple hatch.

The advantages?
1/simple.
2/free.
3/nothing to go wrong.
4/just 2 lines to the tank, feed & pressure/vent.
5/you can drain both the tank & the line to the engine so you don't end up with gluggy, oily fuel clogging the needle valve if you don't fly the model for a while.
