Antifreeze overflow hose size? Any ideas where to purchase it?

Soul Mate II · Nov 22, 2015

Yesterday I took apart the overflow tanks and hoses out of the boat - they had back mold on the inside. I soaked in bleach and water for a few hours. The tanks came out good but the hoses still have all sorts of stuff inside them and I am having trouble cleaning them - easier to replace. What I don't know is what size they are....any ideas? When I go on line, there are so many hose types for different applications. I would like clear - clear that won't yellow or fog up - I see PVC, polyurethane, Kyrdon - again any ideas? Is there an automotive store that will see this by the foot?

Thanks!!!

West Marine might be your best bet if there is one near you. They have a wide variety of marine-grade hoses and sell by the foot. Not sure automotive stores sell much clear hose but Home Depot does.

Antifreeze overflow hose - where the heck can I buy this? Tried Home Depot, no luck. West Marine didn't have it. I have happy to buy the black hose. I was told by SeaRay it's a fuel line hose they use...SAE30r7. Does that make sense?

Thanks- I thought this would be easy.

Been having good luck with autozone vacuum line, it has a thin wall and seals well to the plastic overflow bottle. The thick wall clear OEM tubing did nothing but leak and pricey as well
