Hello to all.I need help! How can i refuel an aircraft tank without an on-board refueling system? I have an electric pump and the required fuel lines.

Is your engine exposed, or is it under a cowl? If the engine is exposed, just pull the fuel line from the carburator and fuel it that way. Before you fuel up, disconnect the line from the muffler. When fuel flows out of the line to the muffler, you know the tank is full.

what do you mean by "fuel system", you can really just buy a fueler valve and fill it up that way really easily, 3 minutes to install, like 5 bucks.

Additionally if your engine is cowled an arguably more reliable method with none of the problems of a fueling valve that costs nothing is to just run the feed line out a small hole in the cowl and right back in half an inch away on its way to the carburator. cut the little loop and insert a short piece of tube and fuel from there. If the muffler pressure line is also inaccessible do the same for it right under the feed line.

I use a pair of hemostats to reach inside the cowl and remove and re-attach the fuel line and bring it out to where I can get to it.
