Simpson Fresh Air Bottle Refilling

Fresh Air Bottle Refilling

How do you guys refill the Fresh Air bottles used on Funny cars.
And how many runs can you complete on a bottle before they require refilling.
Do you refill them from a diving air bottle tank, if so how do you go about this, do you just need drive bottle with a regulator, and connect to fresh air bottle and transfer it.

 

we use a scuba tank
made a hose so we dont have to tank out the simpson bottle
you can get what adapters for your tanks here
we made a 1/4" hyd hose for the line
we just go tank to tank, no regulator
