The losi fuel gun is also clear, the vent tubes do not stick out and it is quite inexpensive. Regarding fuel guns that leak, I really think it hit and miss. If you ask enough people, you will find that every gun leaks and does not leak. My proline gun didn't leak for almost 2 years, but now leaks quite a bit. I saw another proline gun that brand new leaked more than what I thought was acceptable. My losi fuel gun doesn't leak at all, but I have heard people say jus the opposite. Pretty much every RB gun I have seen leaks... I really think it is just luck of the draw when it comes to leaking fuel guns.

Regarding if it is overkill or not I think is kinda strange. First of all, when somebody is pitting for me I ALWAYS let them decide which way to go (bottle or gun). That person has to be comfortable with the method of refueling.

What I mean by it being strange is this:

If you are racing, why not make your pit stops as fast as you can? If you have a fuel gun available then why not use it? With an 1/8th scale I could not even entertain the idea of pitting a car without a fuel gun. Sedan cars a bit more difficult to fuel with a gun.

If you use a Collari-gun or one of the many other brands using the same design you are sure the tank is not full to the edge, the RB-gun is so far I have seen the only one that does it right.

But I have heard good stories about the Team Losi gun, Sirio did use it on the WC....

On 1/8th on road....yes, fuel gun on a average person is still FASTER then using bottle...if used by PRO, even better. Using gun on 1/8th is almost like the ONLY choice, that couple seconds faster DOES matter if you are catching up...(personally experience 2 days ago and that several seconds faster pit stop over a 1/2 hour mains DOES make a hugh different).

On Touring car...yeah, I would say depends on the car's fuel tank, the body, the vent/refill hole size, location and the pit person....it required some practice and design of the refuel opening...I would still think using the gun is faster, but probably not as obviously as on 1/8th.

Also, bottle's tube size DOES matter too...I know there are some bigger diameter fuel bottle can deliver more fuel to the tank (bigger pipe deliver more fuel..) however be prepare to get fuel all over if not handling correctly and also my personal experience (way too many)...fuel over receiver = ran away car or DNF....

i think you should be able to replace the o-rings if your gun is leaking.

I know RB has a rebuild kit for their gun. I probably should try to find one for mine.

Zip tie. My favorite method is a long zip tie attached to the lid and runs back through the fins on the head and is attached to the rear shock tower. To pick the car up you put your palm on the wing, fingers through a hole in the rear window grab the zip tie and pull up. This way with one hand you can pick up the car and open the tank at the same time. Then with your other hand you can fuel the car.

I also do this to all my receivers, but i was surprised to see that a lot of people even in the EFRA 1/8th Euros were using their receivers with no protection.

we use a tab on the fuel tank lid so your hand does not get in the way.


the gun goes in tank on an angle




the end of the gun is 15mm opening on a angle with 5 x 3mm breathe hole "vents". plastic weld is to stop the gun catching on the tank lid so the gun slides in and out easy.



this gun takes a total of avg 3 seconds a fuel stop that is for me to come into the pits get refueled and get out again.

the tank is always filled to the very top edge of the tank.

Not anymore. That rule has been eliminated.

I like the tab on the lid. I might have to make one up for the 1/8th. For TC's I still prefer the zip tie through the shock tower method.
