Pulling the Tank on a 89 SN 2001

The crack was located at the base of the weld where the pipe connects to the top of the tank. The welder thought that the weld was poor quality. I think the thing which amplified the issue was the previous owner was running the boat with an unbalanced prop - which fatigued the connection - very little free play between the pipe and the fill cap. I smelled gas after pulling the boat home. Spent some time trying to locate the problem and finally found it after topping off the tank. All four bolts were tight on mine.

Glad that this is behind me - hate the smell and thought of leaking gas in boat!
Sorry if this is a double reply - i tried posting a message from my phone but it appears to not have been lost.

I found a local guy who does boat gas tank repairs. He did a great job for $60. I went ahead and replaced all of the fuel lines while everything was apart.

Thanks for the help!

Okay, there is a crack at the weld in the top of the tank. Do you recommend having it repaired or replace the tank? Thanks!

It seems to have slowed down, but can't tell for sure - I have a couple of questions - I noticed the hose had wire reinforcement - is there a special hose required for this? Is this a common problem with leakage in this areas? Is there a link somewhere on how to remove the rear side seats?

Can't imagine the tank is leaking at a weld seam and never heard anyone here have that problem but it's always possible. My guess is that the filler hose is bad. Not sure bout the wire reinforcement but it makes since that it does as you don't a weak hose when you're forcing 25 gallons of an explosive liquid thru it.

I'd go ahead and replace it as it is 27 yrs old and remove any doubt. It's only about 18" or so and couldn't be that expensive. In fact wile you are back there tinkering around the fuel tank I'd change out the fuel supply line and replace it with one that's made for ethenol blended fuels. The one installed now isn't.

You could fill up the tank to the point where its flowing out of the filler point and use an inspection mirror and flashlight to look for where the leak is coming from. Be sure you if you do this that it's outside and the floor is up so that when you do find the leak you can mop up the fuel in the bilge and you don't risk all the fumes collecting in the garage. Safety first! If it's the tank then you can see where the leak is coming from there too.


Can't help you on the seat removal as mine is nothing but a bench cushion and the back rest is snaps. Shouldn't be too hard to figure out and I'm sure someone will pipe in who knows. Let us know what you find out.

Its Out ! I twisted the Filler Top with a stilson and kept rotating it and levering the Filler Up eventually it broke free

And I have a question? you have LPG and gasoline and I guess you can just switch between them? I figured it was just one or the other but not both.

Recently did this on mine and found the easiest way was to cut the filler fuel line perpendicular to the neck to release it. The rubber tends to get hard and baked onto to filler neck. Be careful not do damage the aluminum so you don't get leaks when you put the new line on for re-install. After cutting the line, tank should swivel out pretty easily. Make sure you siphon as much gas out as possible so tank is not too heavy.

Tnaks for that Morfoot I have two Tanks ( just to be sure !) Petrol as original standard and LPG in front I have successfully loosened the LPG ready to move it to the side so its the standard petrol behind that is next . At the moment here in the UK it is raining dry for 10-30mins then raining its been like that all week and same for next 3-4days I'm waiting for a 3-4hr dry spell to get in there and pull the tank and get it lakeworthy when ....... the weather and the sun comes ?

Boyd, the gas tank should be held in place by two steel straps just inboard of the main stringers I believe. You should only have to remove the nuts of the threaded portion (that was welded to the straps). Pull the straps up and slide the tank forward once you get the fuel vent line, fuel supply line, and wires to the fuel gage removed. Should be fairly easy but no guarantees.
