Bay Runner – I used the continuous hoses with the bulkhead adapters built onto the hose similar to the one at the top right of this link.

I installed a Sea Star system but used another manufactures hose kit. It was less hassle and parts than running a hose to the transom, making a connection at a bulkhead adapter, then using two short hose pieces from the transom back to the motor. Also made the length adjustment from the transom to the engine easy.
Here they are installed -
Hope this helps..
