Actually you don't want that style and here's why.
Any chafing is going to occur where the hoses are exposed in the splashwell.
Those hose's are one piece. Even the support deal is attached to the hose.
A better setup is 4 hose's and a bulkhead fitting kit. The 3/4in kit should work fine for this type install.
The advantage is this. if a hose is chafed that is exposed it's a quick and easy exchange to change a 2fy long hose and you don't have to pull the whole hose out of the rigging.
That's how mine is but with a bracket and going thru the transom I have the 3in bulkhead fitting's.
Here's the Teleflex part #'s.
Bulkhead fitting kit = Part # HF5512
Here's the page to pick the part #'s for hose's.

Surplus Unlimited in Daytona has the best price's. They beat the price's I got on 3 other quote's and that included having to pay Fl. sales tax.
