Why don't you use a syringe as the piston? It would have a near perfect seal.

Good point jack, but now I have a better idea.
Go to a $2 shop and buy somthing like this:


I used to be able to buy cheap versions of these for about $2. If you cut the end off the pump it would give you a good piston and a tube that it fits perfectly in. Best of all it should have fairly low drag.

well i have 1" conduit, that 3/4" conduiit slides in like a glove. i was thinking of using that and possibly cutting a groove for an o ring in it.
