sstout Posted December 28, 2014 Report Share Posted December 28, 2014 Hi allI've just bought a Sherco 290 2002 model, the fuel tank had some black goo around the petcock, as it was leaking a lot, I decided to scrape it off to see what the problem was...turns out the tank is made of a soft plastic/polythene & the petcock doesn't sit flush against the tank base. As the plastic is pretty flexible, (it flexes more at one end than the other & has a bow in it). Does anyone know of a way to seal this? some type of polythene glue etc??CheersSteve Quote Link to comment Share on other sites More sharing options...
darrensn Posted December 28, 2014 Report Share Posted December 28, 2014 Hi, you could buy a small sheet of 3mm thick EPDM rubber and make a gasket to go between the tap base and the tank. If you have a good thread on the fixing it should pull it up ? Here's a link to one on eBay, 100mm sq x 3mm thick = £2.40 delivered. http://pages.ebay.com/link/?nav=item.view&alt=web&id=121210592045 Quote Link to comment Share on other sites More sharing options...

burns1989 Posted December 28, 2014 Report Share Posted December 28, 2014 To me it looks as if the trade insert has pulled out causing it not to sit flush I would remove the pet cock and see how flat the tank is with a straight edge . And it looks like some one has tried to melt the tank to get the thread insert out hence why the petcock is not sitting flat . To be honist you best off buying another tank as you will waste your time trying to seal it .I know this is not what you would want to hear but saves a big disappointment of it leaking all the time Quote Link to comment Share on other sites More sharing options...

sstout Posted December 28, 2014 Author Report Share Posted December 28, 2014 Hi Folks, thanks for the info, I've made a temporary repair with some tube rubber & some foam, I'll buy some of the EPDM rubber as suggested, then if that don't work I'll start looking for a new tank... Really appreciate the time you guys took to reply... thanks very much & happy New Year to you all... Quote Link to comment Share on other sites More sharing options...
