Car fuel tank for boat?
Submitted by linoc on Mon, 2017-12-18 13:47
Hi guys, done a bit of searching, can’t find anything related.
With concerns of air, moisture etc with boat tanks, is there some reason why we can’t use a car fuel tank, being it’s closed off to environment etc?
Was thinking of setting one up under floor, perhaps add a one way air release valve to allow vent off when required, but not allow air/moisture in.
Cheers!

Air needs to be able to enter
Air needs to be able to enter and exit the tank or it will implode.
Don't think car tanks are really made for the pounding....

Car tanks are steel,even if you put it under the floor salt moisture will get in and rust from the inside.

Go to ARB or a dealer, we
Go to ARB or a dealer, we throw away old hilux tanks when we fit long range ones, could pick one up cheap or free.
They have breathers etc so no reason you couldn't setup like a boats. My boats are vented at the top back of the transom with covers so water can't get in (unless your underwater).
Genuine tanks can take a beating, I've seen them crumpled into themselves when the breathers are blocked and smashed up badly by rocks with no leaks. Aftermarket are too rigid and will crack whereas genuine are flexible (plastic).
Just my 2 cents as have thought about this before

Yeah as niko said
Provided you fitted a genuine plastic tank, I reckon you would be right as rain.
Just make sure it is well supported underneath the floor and you will be fine. Most modern car tanks will have a efi pump and filter already installed also.
Let us know how you get on if you go ahead with it.

Thanks for the reponses, been
Thanks for the reponses, been a bit busy this week getting ready for a couple of weeks off so havn't had much time for play, a bit of searching during breaks I found these - http://www.autoforcewa.com.au/product/20-gallon-76l-fuel-cell-with-cavitysump-fuel-sender/
Apparently the joins are welded by robots for strenth and accuracy, used in drag cars so should be able to take a bit of rumbling. Aprox $400, not sure what it would cost to get one customed?.
Hilux tanks sound interesting Niko, might check that one out
