Does MERCRUISER use the same hoses as the OMC / VOlVO on this 4 cylinder ?

Not Mercruiser, however VP may be close

What I would do. Go to gates website. Download the molded hose catalog, them measure your existing hoses, and spend a few hours finding the hoses under the gates numbers

I took the gas fill hose (and maybe the vent too...) from an old truck to Napa. The counter guy took me back to their impressive radiator hose supply and we found something that worked (prob had to cut it down).

Might notta been the right thing to do (use a rad hose for that), but it's held for a few years now.

Another option...

Now, I'm looking for fuel hose, not cooling hose and my old one says, "Shields 310 USCG Type A Hose Fuel Fill 1983". Don't think any NAPA store has a Type A or A2 one that is USCG approved.

Yes, boats are another matter; don't make any substitutes when it comes to the fuel system.

(To continue the topic shift/hijack)... That does look old; Can't readily access mine to see what it says on it. Looks heavy duty though and not ribbed like that. Black w/lengthwise maroon stripe (for what that's worth).

Cooling system on most marine engines is not under pressure.-----Temeratures are lower than automotive as well.
