smig Posted December 12, 2021 Report Share Posted December 12, 2021 Hi All The petrol tank on my Gasgas gp 280 has expanded to the point we’re it is almost impossible to get it in. I was wondering if the 2012 aluminium tank would fit ,it looks to be the same apart from it being a little higher We’re the fuel cap sits. Has anyone tried this modification, I don’t really want to go spending on another plastic tank for it to do the same Any information would be much appreciated Cheers Quote Link to comment Share on other sites More sharing options...
sherpa325 Posted December 12, 2021 Report Share Posted December 12, 2021 (edited) I had the same problem with mine. I found out that the fuel I had been using had ethanol in it and after changing to a non ethanol fuel, the tank over a period of time returned to its original size. Sounds crazy but it's true.[10% ethanol] Edited December 12, 2021 by sherpa325 Quote Link to comment Share on other sites More sharing options...
UG_ALLSTAR Posted December 13, 2021 Report Share Posted December 13, 2021 The fuel petcock is different on aluminum tanks so if you go that route you'll need the petcock too. Quote Link to comment Share on other sites More sharing options...
pjw123 Posted December 14, 2021 Report Share Posted December 14, 2021 Modern Ethanol laced fuel causes all kinds of problems with plastic tanks, O rings, seals ,etc. Solution is to remove the ethanol from the petrol. Easy to do, as Ethanol readily co mingles with water. Slight downside is that you've got to chuck away the ethanol you've removed . Check it out on You Tube.

And the fuel you are left with is damn poor stuff, looses about 3 points of octane rating. Best to just buy proper fuel to begin with. 1 Quote Link to comment Share on other sites More sharing options...
