I've got a Pro-line gun that i got off ebay for less than $20 shipped to my house and it works great. What we usually do is save that empty gallon jug and fill the bottom with some rocks, after you fill the gun with the small fuel bottle-then set the gun in the gallon jug and wait for pit time. As long as the fuel doesn't get into the vents it doesn't leak, and after some practice you can really knock out some pit stops.

If your proline gun is leaking and it isnt because you've let some fuel over flow the vent tubes.....take the gun apart and check the entire length of all the vent tubes. There may be a crack or split in one or more of the vent tubes maybe half way up.

I had this happen to my gun and found out it was a split in 2 of the tubes. A bit of solder and now its leak free.

The oring on the nozzle of the proline gun us usually good.

Never used or seen a fuel gun before but just an idea i have.
Why not run some tubing into a T-Piece and then fit a one way Check valve to it. Then it should never leak no matter which way you tilt it and it should still retain good flow.

Something like in this picture:

Most new cars have a check valve fitted on the windscreen washer bottle line to stop the fluid running backward into tank.

Dunno if you can hook something like this up to a gun but hey its just and idea so dont flame me for it

A guy at the tracklet me try his brand new Losi gun that he had never tried. The plunger was very slow to return to the closed position and spilled every where.

Well, I got my Losi gun. Impressed with the quality and the tight tolerances of the fit.

Doesn't seem to leak when it is upright. Does seem to leak if it is tilted - even slightly.

My buddy wondered if replacing the O-rings inside it with fresh ones would help. He was saying that certain o-rings can deteriorate rather quickly if they've sat up on a shelf for a while.

We didn't really use it during the race because my pit guy thought he'd be faster without it.

I think I need to build some sort of PVC holder for it and set it up on pit row when we race (I.e. to keep it completely upright).

Anybody have any thoughts on this?

Cool

I used a Losi one at the 2007 Smackdown race where i pitted for a buddy of mine. We used the gun the first 2 pits and went back to the bottle the rest of the race. I was not impressed, I think the bottle is just as fast.Also the gun leake if it had any fuel in it. If your pitting two guys wich i have more than once, trying to refill the gun can get to be a hassle.
Just my opinion.

My buddy made one for himself and another guy and is making me one soon. Its perfect, he even put a metal plate that sticks out the back so it can sit on pit lane underneath the goodyear rubber tubes that are nailed into our pit wall.

I'll get a pic when I get mine.

I love my Losi gun. Yes it leaks, only when fuel gets in the vent holes...which is usually when the gun isn't upright or is overfilled past zero. It's easier to aim with and hold, doesnt overfill, and tells you how much fuel was put into the tank.

I can do all that with a bottle except the over filling part.

And tell you exactly how much fuel was put into to the tank.

It's just personal preference.

The problem with the bottle is that it doesn't insure that the tank is filled completely. The fuel gun still has some problems, like leaking, but it does fill a tank without question.
