If you don't like what the engine is supplied with (I am guessing tygon anyway) you can buy your own at nearly every hobby shop:

or

Also make sure that whatever method you use to supply your model fuel has the same type of tubing. I use these for gas:

but you can make your own fueler on the cheap.

The engine is supplied with 18" of black FPM (viton) tubing. This is not neopreme tubing. We worked at sourcing the FPM so our users would not have to deal with the stiffness of the tygon, and tygon tubing used inside small fuel tanks is absolutely useless as a clunk line. It is so stiff it never lets the clunk move.

The only thing we didn't provide was a gas proof stopper for your fuel tanks because of the number of different tank styles out there.

Shoo - the tank that comes with the H9 P-40 has a stopper in it that is gas compatible. In some installation we have replaced the 11oz tank that comes with it with an 8 oz tank and then used the extra room to mount the ignition and/or ignition battery. 8 ozs will get you 24 minutes of wide open flying with the 10cc. For planning purposes you should expect 1/3 oz per minute of wide open flying time.

The smallest tank we recommend is a 6 oz ... below that and there really isnt enough room for a clunk to move around and be effective.
