This one is crap becuase it cracks on the silver spool and the whole thing was damaged. Go for RB or Kyosho gun. Both are good, especially Kyosho ones when they changed the small tubes to copper tubing, it won'y crack like the brass ones.

I've just bought a new kyosho fuel gun. It's very good and it does not leak if you keep it vertical when it's full. The main problem is that the trigger does not close the cooper tubes (where the air enters during the refuiling). So, if you point the fuel gun up and then point it down, a swall amount of fuel leaks thru the tubes. Moreover, if fill the gun and and keep injecting fuel, it also leaks from the small tubes. However, it is a problem of all fuel guns. All of than works like this.
When it starts leaking thru the main hole, you just need to change 2 orings and it will work like a new one. The only thing I didn't like is the fuel capacity. The kyosho gun holds only 1.5 tanks of fuel.

my 2 cents...

You need somthing to keep the pit guy from falling asleep during the race

It is not a problem, that is the design. The guns are meant to be propped up vertical until they are ready to be used. See http://www.rbproducts.com/mainEn.php...Messina(I).htm down on the left. The RB pit box is designed to hold the fuel gun upright. If you don't have the fancy pit box, many people just cut open an old fuel bottle for a drain and hang the gun over the side. Not too messy at all.

The small tubes are vent tubes and their design is twofold. First is to let air into the main body of the gun so fuel will actually come out at a reasonable speed. Second is to stop the flow of fuel once the fuel level reaches the vent tubes.

Not saying you, but many people have bitched and moaned about leaky fuel guns over the years and really don't know what they are talking about. The tool is what it is and yes they naturally leak a little. Get rid of the vent tubes and try your gun and you'll find it doesn't flow but a dribble. I'd rather have the faster flow, wouldn't you?

Hey Fraz:

I didn't express myself well, sorry but my english is not good. I agree with you, it is not a problem, it is the design. I understand the function of the cooper tubes, the air enters thru them allowing the fuel to go out of the gun.
I was trying to explain that the fuel gun does not leak if you use it right. Most of the peaple thinks that the fuel gun is completly sealed, which is not true.Maybe in the future the designers will put a kind of valve on the copper tubes, blocking them when the trigger is not pressed.

How about a sealed unit that uses a CO2 canister to dispense the fuel. You could even have an adjustable valve to control how fast the fuel comes out.
