rick rexroat Posted June 2, 2016 Report Share Posted June 2, 2016 I have a 2002 Sherco 50 and the fuel tank is leaking. I tried patching it with epoxy, fiberglass, fuel tank repair, and even plastic weld it and the best I could get was about 3 months use then it starts leaking again, I tried to buy a new gas tank here in the United States but no one has one, So I'm giving a shout to you folks in Europe to see if you can help, PLEASE Does anyone know where I can buy a fuel tank for a 2002 sherco50?

reggie Posted June 2, 2016 Report Share Posted June 2, 2016 It may help if you let the forum know exactly where on the tank it is leaking. Quote Link to comment Share on other sites More sharing options...
wmc37 Posted June 2, 2016 Report Share Posted June 2, 2016 I had the same problem I think, on mine the adhesive that holds the petrol tap boss in deteriorated and subsequently caused it to leak. As you have done, I tried everything but because the tank is flexible it soon cracked and started leaking again. I did source a new one through Malcolm Rathmell Sport but that was about 2 years ago so I don't know if they are still available. In the end I was told about a substance called SIKAFLEX, Its like a black mastic but much better. Its flexible, sticks like s--- to a blanket and seems to be petrol or Benzine resistant. I sealed the tank probably 2 years ago and its still petrol tight. Hope this is of some help Quote Link to comment Share on other sites More sharing options...
rick rexroat Posted November 23, 2018 Author Report Share Posted November 23, 2018 I finally built a tank out of aluminum. Works fairly well I did loose some capacity and I had to insulate it from the heat of the engine but, I'm not fighting the leaking petcock mount.
