fuel feed idea help?

[babi_hrse]

right i have this idea i have halfway thought out. i have a screwed in fuel cap on my nitro touring car what i want to do is add a extra line to the fuel tank by drilling in a hole and adding a fuel nipple onto the tank from the top. this would allow me to refuel the car without taking the shell off and adding to the scale realism. i would fuel the car via a hose to the fuel cap and a winding fuel pump. the only problem i realised when i bought a Y shaped adaptor is it would be allowing the exhaust pressure to bleed out and would cause fuel pressurisation problems... does anyone know of a <takes a deep breath>:whhooo: one-way-valve-fuel-nipple-for-rc-cars? that would do the trick?
surely someone in the heli community must have heard of something?

You can buy plugs designed to fit in the end of fuel lines to plug them off. I use them when I can't run out a tank of fuel in one of my nitros and dont want to waste the fuel because I know I'll be back out again soon. I took the fuel line off of the carb and let it run out and then plug the line so the fuel doesn't leak. I dont see why you couldnt use one of those plugs so the backpressure doesn't escape. They arent the easiest things to remove but thats the only idea I have for you that would make it possible to do what you are talking about.

I think that they have something likr you're looking for in the aircraft side of the hobby.

Correct. We use these on planes. The nozzle on the bottom goes to the fuel pump line. When it's snapped into the top of the filler valve the fuel goes directly to the tank. When it's removed the valve closes and the system returns to normal.

hemm this seems doable... whats the third nozzle for?

That's the standard fuel flow from the tank to the carb when the fill nozzle is removed.
When the nozzle is inserted into the valve it runs fuel to the tank and blocks off the carb line.
