1986 bayliner capri 2150 leaking gas-gctid802883

[Asharpe0687]

Hello all,

I just recently purchased a 1986 bayliner Capri 2150 with an Inboard/outboard. I started the engine yesterday and let it run for a little while before getting it into the water for the first time in a few days... this is my first boat and I am learning a lot along the way. Today I noticed that there was fuel leaking from the gas cap and under the leg. Anyone have an explanation for this? I have read that it could be the gas expanding but the tank is reading half full... also the boat is angled back toward the stern. Any info would be greatly appreciated.

Thanks,

Al

None of this makes sense. The gas cap is leaking? Under the leg? So the fuel is coming out from the outdrive?

Need more info. WAY more info. And possibly pictures.

It is leaking from the gas cap. When I take the gas cap off gas poured out. It is also leaking under the outboard.

There should be a fuel vent on the stern, outside. It has a fine mesh screen and can get corroded or clogged with bug nest material. Easy to remove and clean or replace. Also, check the fuel fill hose, mine failed after 17 years. Be sure to flush the fuel with a lot of water, it's very volatile.

Sounds like a plugged vent as others have said. Was it warm the day you ran it? You may also have a stuck fuel sender causing a bad read on your fuel level.

Interesting.

First of all, you have a Ciera, not a Capri. It's a 2150 Ciera. Not that it makes a HUGE difference, but the layout is different.

Secondly. agreed you likely have a vent issue. But the fuel dripping out of the drain hole under the outdrive is also cause for concern. I would try to see if you can get in the engine compartment and see where the tank is leaking from.

In a Capri (a bowrider), the fuel tank would not be as visible. In a Ciera, you should easily see the tank. It is the aluminum tank immediately in front of the engine, which means you should see if there is an external leak from a hose or a fitting.

If you cannot find the leak, then the tank itself is likely shot.

In other words, you might have 2 issues - the vent block issue, and the tank leaking issue.

You are correct. All my paperwork says Capri and I didn't even think twice about it. Right on side of the boat along the glass it Says ciera. It's hard to even get to the gas tank... I can definitely see it. I am going to check all the hoses now. As for the screen, where is that? Again, bare with me as this is my first boat..

Thanks.

I just checked the hoses and I don't see any leaks... I checked the hose going into the tank from the gas cap and also the hose coming out of the tank to the engine. Everything seems right and secure. There hasn't been any other leaks or even smell of gas... could it have been a fluke thing on a warm day?

This is a typical fuel vent, usually mounted on the transom.

+1 there is a third hose from the tank that leads to a vent fitting mounted through the hull. It'll be a 5/8 diameter rubber hose leading to the fitting that wgander posted.

I agree that the fuel cap issue is related to a clogged vent.

Fuel coming out of the drain plug means there's fuel in the bilge. This can be a very dangerous situation as it could lead to a fire. Make 100% sure that you do not have fuel leaking into the bilge before you use the boat again.

On the Cieras, the vent should be immediately below or near the fuel filler on the transom. It will have the small chrome fitting linked above. It;s simple, just trace hoses to the transom. ALSO - consider replacing all fuel hoses at this point. They are nearing 30 years old.

I agree with Norton....fuel in the bilge is dangerous, and serious.

I would consider pressure testing the fuel tank at this point to see if it's leaking. If it is, the tank needs to be R/R'd..it's a big job,
