Irrigation Injector Hose-size Help?

[CCinPA]

I need a 1-3 foot garden-type hose female-connectors both ends.

Then... Most importantly the least possible flow-rate resistance.

Help?

If you need a rigid pipe this is all that is available, 3/4"pipe and make your own.

If you need a flexible hose, then washing machine hoses are usually 3'.
