The tank is for a Impulse Pro, it is a 75cc tank. I too could only get about 4 1/2 to 5 min a tank. We race on a real short tank with over half the track tight turns so there's really not much speed so that may be why we gain 2 mins. Like motorman said when you are off the throttle with the stock tank it blows the fuel out the pipe. Now all the fuel is used not waisted.

I will chck the hobby shop this week for a tank, they carry full line serpent. Do you still move the pressure port or is the location OK

I may modify this stock tank for the lid pressure nipple as I did with my XXX-NT.same problem with those as with this tank is the pressure goes into the fuel and foams it then allows fuel to escape the pressure line.

So the question becomes.........can you just modify the stock tank with a new pressure fitting in the cap to do the same as putting on a Serpent tank? Seems like it would be an easier solution than having to put on a whole new tank with custom mounts.

Motorman,

Can you post a pick of your tank lid mod?
We have seen Old Skool's mod to the side the the neck,
I just want to see where you placed it on the lid.

Also, how much clearance do you have under the lid?
(how far does the pressure nipple extend through the
lid into the throat of the tank?

With this mod, you do not run into any difficulties while
the lid is open during refueling, or after closing the lid?

You can get by, by just doing the lid mod, it helps alot but it still fills the carb line with tiny air bubbles and makes it hard to tune. The serpent tank mod is a perfect fix,. No fuel out the pipe when off the throttle or no air bubbles in the fuel line. The lid fix has been around for years and it seems to work ok, hell car action done the same mod to the GT tank a year or 2 ago. I don't want to take chances of burning up the RB's since they cost so much so the serpent fix was a cheap insurance, hell it takes a total of about 10 mins to retrofit, its not that big of a deal!

I did it with the Losi tank and it works great.Retro'd the lid in the top of it to fit the nipple and offset the underside of the lid.
In fact I will try it now with this one.

yep looks just like mine except for the blue nipple I used.
I then drove a set screw into the old tube and cut it down so as to plug it off without an ugly screw popping out.

This may be a stupid question.......but approximately what size screw are you using to seal off the former pressure location? I'm assuming if you use one too small you'll develop an air leak and if it's too big it will crack the tank again causing an air leak. Just figured if I had an approximation as to the size used I wouldn't have to worry about that stuff

On your 90 degree fittings are you just drilling a small hole and then threading the nipple into the tank or do you have to seal it with something as well?
