My Seacraft

[TomParis]

So I replaced the corroded battery cables and got it all cleaned up and ready to run. Motor ran good in yard and then I smelled fuel. I check under the deck hatch and I have fuel in the section where the tank is. So the question is two fold, one is it safe to keep running the boat? And 2 my aluminum tank is only like 5 years old is it likely that it has a pinhole in it already? The fuel hoses are getting older, but the one that runs to the motor is staying pressurized. The fuel fill hose and fuel vent hose are older than the hose that runs to the motor, but I didn't put any fuel in so I doubt its either of those hoses leaking.

I may even consider off loading this boat at this point.

Sigh

Find the leak(s), fix the leak(s) and run it. But not until then.

How full is the tank? I am helping my parents with a similar problem on their 18 SeaCraft. Their situation is a clogged vent hose and the majority of the fuel going in the bilge when the marina topped off the tank last weekend. I’m pretty sure Gfs had a fill hose that was leaking gas. Seems like I recall someone saying that when the tank is totally full, fuel can get back into the fill hose and the leak if the hose is compromised.

I dried the area so I will be checking it tomorrow to see if new fuel is there. The tank is currently about 3/4 full. I will take some photos of everything perhaps you guys will have some suggestions.

The fill and vent hose on mine were dry rotted and cracked severely. I would be surprised if a tank corroded that quickly.

I had fuel in the bottom again after drying it out yesterday the boat hasn’t moved so could a fill or vent hose that is bad cause fuel to leak out if the boat didn’t move

[TomParis]

I checked the fill fuel lines and the vent hose line both are dry. As I said they are older and I will gladly replace them but I am worried that the leak is not from them. How do I go about getting the tank pressure tested? How do I get all the fuel out to be able to remove the tank. It looks like a 20 - 30 gallon aluminum tank. The previous owner said it was installed a year before I bought the boat. so around 2014 to 2015.

been watching videos on youtube on how people don't install the tanks correctly and they use foam (which mine has) and how air cant get in and dry the water and the water slowly eats a hole in the tank and then you have a pinhole.

Worse if this is the case for me, then it sounds like you are replacing the fuel tank as it is unrepairable.

Sigh...
