North Australian FISH FINDER TM forums

My 120 liter underfloor tank seems to have a crack in the weld of the inlet pipe. Tank is aluminum.

I have exchanged the hose from the filler cap to the welded pipe which sits on top of the tank.

When the boat is elevated backwards, there is fuel leaking from the area next to the pipe.

Is it possible to weld a fuel tank which has had fuel in it ????? Obviously it needs to be emptied, but there will be fumes sitting in there for ages I would assume ....

Who does stuff like that in Palmerston?

Cheers

George at NT Unique is a good bet pops

You can save $$$ if you lift your floor and remove it yourself

It's a walk-on aluminum tank.

I've had it out before ......
It's only 8 screws and 3 hoses ....... easy as .....

Done them before.........flush with detergent a few times......Keep flushing until no fumes are smelt then flush again......morning fresh is fine

Does it matter if it's only fresh pine instead of morning fresh ?????

Get it done by someone who knows what they're doing
All fuel tanks should be purged with a non explosive gas and oxygen levels of purge should be below 1% while welding
Some people get away lucky by using other methods ,some don't
You have to ask yourself DO YOU FEEL LUCKY

Removal is the easy part. The welding I suggest you get done professionally. Fuel/fumes in the boat is not ideal. One way to clear fuel tanks of fuel fumes is to run a pipe from your exhaust into the tank, once emptied of course, for at least 10 mins, but that will be up to the repairer. Good luck.

Don't worry .... just joking around.

Removing it is the only part I would do myself. Everything else would have to be done professional anyhow, as I don't want to blow myself up ....

George at NT Unique. Good bloke and can weld.

George from nt unique x3. Do it right the first time at a reasonable price.

Thanks for the tips guys ..... I'll have a look at it after the Easter break and get that tank emptied ....
