I need to get a hose and not hosed in Newport

I think I've narrowed down the raw water system leak on the port engine. As I mentioned the other day, I suspected the feed for the port shaft seal. I started up the port engine today and let it warm up and revved it up to 1800 RPMs and went down to the engine room. The fitting at the oil cooler for this line had a "significant constant drip" (that's a technical term).

I pulled the cooler off again and pulled this line off. Here's the fitting:And on the inside of the fitting:

Here is the writing on the actual line:

I'm not sure where this fitting is leaking but it is obvious it is leaking. The green corrosion shows where the salt water has been running on this line. The inside of the fitting appears to have some corrosion but who knows... I just know I need a new line made with this fitting on one end. The actual line has a 3/8" inner diameter and the fitting has a 5/8" inner diameter the goes on the cooler. The shaft seal connection uses two hose clamps on some brass fittings.

Oh yeah... note to self: Next time you pull the feed line off the shaft seal have something to plug the connection as it is 3 feet underwater.
