plastic or stainless tanks

Due to me having a leak in one of my stainless tanks I have had to cut the deck up to get to them!

Now, the dilemma is; do I repair them or go and get a couple of plastic fuel tanks from Tek Tanks?

Is there a benefit to having stainless ones over plastic or is it just gucci to have stainless ones?

I dont want to have to go through this expense again if it could happen again.(which it has!!)

Thanks

I think it's best to construct aluminum tank. So it will have less weight

DONT GO FOR Aluminium tanks in a RIB. They will pant and spring leaks quicker than you can say"how much?" each tim eyou fill it up. The Ribtec used to suffer with breaking baffles in the inside the tank which inturn caused the area to leak from the weld. Cut the top off and get a good welder to seam weld the baffles then put a new top on. Job Done Alan P

Hi

with an aluminium it depends on the build quaility so they are both right. Plastic though is by far the less risky option in our opinion.

Was that stainless ribtec tanks? The boat is a ribtec, not sure about the tanks though.

That's a bit of a sweeping statement, hopefully based on your experiences from a crap tank builder!

Go to a company such as "the tank company" in Poole, and you won't get a problem. I've been using them for 15 years, and never had a failure. Not cheap, but quality never is. If you work on the formula of 2.5 x the cost of the fuel (petrol) the tank holds, you won't be far out! Assuming it's a pretty uniform shape of course
