It should definitely say that it is approved for gasoline, otherwise it is against the law. I'm not even sure you can buy metal ones any more. All the ones at the marina I go to are plastic.
On small trailer boat over here, the majority (over 90%) of us use plastic Quicksilver (type). <br />Being a trailer boat, we usually take the tank to the garage and fill up with petrol and take it back on board. The number of trips means after a while the bottom of metal tank are scratched and starts to rust and it will mark the grp.
