Safe Gasoline Tanks?

Someone told me there are "safe gasoline tanks" that cannot
explode because they have honeycomb-like inside.

Does anyone have experience with these?

Where can they be obtained? How large are they?

Re: Safe Gasoline Tanks?

Even safer still is to not use gasoline since you don't actually need it for any practical purpose.

Re: Safe Gasoline Tanks?

on a boat generally it is not the fuel tank that is the problem,it is fuel vapors that explode.
lots of info on the net if you google "bullet proof fuel tanks"

Manufacturers Bulletproof Explosive proof Fuel Tank India, Sobti Group - Laggar Industries LTD - manufacturers bullet proof vehicles india

Re: Safe Gasoline Tanks?

Okay then. Another question:

Does anybody cruise with a gasoline engine?

How is your fuel kept?

many smaler boats use outboards in wells,and off the stern.
fuel is generally stored in the "self bailing" ,cockpit or dedicated locker in a standard plastic outboard tank that has bayonet fittings for the fuel line and a vented,but sealable filler cap.

the main consideration is that any leaking fuel or vapor,cannot being heavier than air,find its way to the bilges of a yacht or boat.

Re: Safe Gasoline Tanks?

Whether or not gas is going to explode depends on whether or not it is between the upper and lower explosive limit, meaning you have to have the right ratio of fuel vapor to oxygen. Gasoline fuel tanks accomplish this both by keeping the fuel vapor to oxygen ratio too rich and/or preventing a source of ignition. I don't think a honeycomb structure would have anything to do with this.

Gasoline tanks kept outside where the vapors cannot accumulate are considered relatively safe. Gasoline can be stored inside in a USCG approved gasoline tank that is also installed correctly but you must also have a blower for venting possible vapors.

Personally, I don't like seeing gasoline stored inside on larger boats. It is just too dangerous. Any gasoline I have to bring aboard the research boat is always kept outside.

Re: Safe Gasoline Tanks?

yes i have met cruisers who cruise with gasoline using atomic 4 engines. some actually use their engines some of the time.
have yet to see a rag boat with gasoline fuel blow up---they burn like the worst thing on earth--hot and fast--have seen that...but not boom.
boom happens when tank becomes too hot --after the boat is so involved you have already abandoned it.

i do cruise with a gasoline outboard stowed. i keep gasoline in jerry jugs on my coach house roof, tied to mast and handholds. no i do not worry about them exploding or burning.
