I remember seeing a thread recently that had the dimensions of the 3 inch (?) hoses that go from the cowlings on the transom into the dumpster for ventilation. Can someone point me in the right direction or tell me the lengths and diameter of these hoses?

Thanks much!

Can't point to the thread. However, I recently tightened the clamps on mine, and the hose sure looks like 4-in.-dia dryer hose.

Take the gas can out, put it on the floor of the cockpit, toss the hoses.

That's what I needed! 3" I.D. One is 5' and the other 9'.

Thanks!

I'm 80% done with a permanent gas tank install and I want to keep the vent hoses. I've been spending a lot of time in the dumpster and I am amazed at how much air moves through the hoses even while sitting in the middle of the woods on a trailer.

Yup. Catalina has good designers. You might want to use one of these where the bottom hose comes into the dumpster through the bulkhead. Keeps the hose from accidentally collapsing.

I like it! That will definitely help the hose last longer. Cheap, too.

I would permanently leave my tank in the cockpit, many boats do. I would get the bomb out of the dumpster... that's just me.

I'm actually really pleased with how the project is going. A permanent below-deck tank is also a very common thing in a boat and if it is done properly I would argue that it is more convenient, cleaner, and just as safe as a tank in the cockpit. I'll have 12 gallons of fuel and full use of the cockpit. I'm going to put a basket on the old fuel shelf for my dock lines, winch handle, etc. I think this will be a big improvement in many ways.

Todd,

Over 10 years ago I converted my 1979 C-25 to a 12gal inboard gas tank as well. I subdivided the 'dumpster' at the same time to make the space more usable. If you haven't already done so, I suggest you read up on boat building standard practices, legal and safety requirements for inboard fuel tanks. Particularly ventilation and hold down requirements. In addition to the vent hose for the tank interior, I built a close fitting box around my tank, and ran two vent hoses for the box. Sort of a mini version of the stock dumpster vents, complete with little fore & aft facing air scoops and corrugated plastic hoses.

Leon, I did just as you suggest. Another member pointed me to the regs and I have studied them and adjusted my install accordingly. For anyone else that is interested, here is the URL
