Dead common in boats, OEM in many cars but I've never heard of anyone using them in a locost. Why?
They are cheap, light and readily available. There must be a reason I can't think of why I shouldn't use one - do the SVA frown on them? Fitting is dead easy just use small ratchet straps to clamp them in.

Oops. Me and my big mouth - open first think later. Just done a search and found there are threads on the subject already

I still think that there's scope for using the plastic tanks commonly found in speedboats, if one can be found that fitted the back of a Locost.

They're very tough! I'm sure that they would withstand quite a hard impact without bursting.

Actually very common in Locosts but a couple of people have had problems with leaking seams the Locost ones are fabricated by plastic welding.


Off the shelf boat tanks are just a bit too wide to fit in the back of a Locost unless mounted high up.

There was a chap making and selling plastic tanks for 7's but he made a bad batch (not his fault.... he used dodgy sealant stuff) and it all went a bit 'pete tong'. I'm STILL waiting for my refund as my tank leaked, guess i'll never see that money again

OEM plastic tanks are injection moulded to the required shape and only have one seam which has a big flange round it for easy sealing.

Fabricated plastic tanks are made from flat sheet and have several seams with no flanges. It is harder to weld plastic than aluminium.

Ive got one. No problems to date. had fuel in it for about 6 months. Been on road for 3 months.
I wont say where i got it from as im in danger of being accused of being linked to them!!!!! Thanks Mark And Colin (#1)
