I'm close to the 'good' auto parts store, and far away from my car. Can I get a couple of measurements???

What size is the 'heater hose' inside the car, and inside the engine bay? How much do I need to do the engine bay, and the longs to the front 'firewall'?

Also, what size is the windshield washer hose? I've got new sprayers, but need to re-fab all the hose to the pump I bought, and then to the resivoir.

Thanks gang...
