As stated above there is a normal barb under the crimped fitting in the tank strainer. You can cut it off and put a normal piece of hose on. I'd suggest the SAE 30R9 hose. It's lined with viton and much more durable than solid viton. The barb fitting threads out of the tank screen, so you can take it off and work on it. This would also be a good time to remove the tank strainer and clean it. Make sure to put on a new o-ring before you install the strainer back in. I'd replace both the supply and the return while you're under there so you don't ahve to do it again.
