Aluminum Nipple is designed to fit in all Sullivan tanks. It can be used for an extra fill or pressure port, and will accept standard and large tubing. This nipple will also work with bladder systems.

S476 Fuel Tank Nipple



Put this in the back of the tank and just hold the plane up when draining. Or put a regular fuel stopper in the backof the tank. Or even better put the fuel dot in the side of the plane and don't hook it up. Just to be cool.

If you get a slant tank you should be able to get three line in it.

Good Luck.
