Jiminy Cricket Posted April 16, 2012 Share Posted April 16, 2012 Before I knew better when replacing my rear cross member on my 110 i also renewed the tank. Sadly I bought a Britpart one, complete with new sender.......it leaks! I have changed the sender, changed the olives and changed the rubber seal and metal seal ring twice. Switching the seal over does seem to stop the leak, temporarily. So I have concluded that the tank hole for the sender is imperfect (true Britpart quality) and thus leaking - can I use an RTV sealant on this - will that work, or am I doomed to have a leaky tank till i stump up for a new one, not made by Britpart? Any thoughts or suggestions on how best to fix would, as ever, be greatly appreciated! Quote Link to comment Share on other sites More sharing options...

Dave W Posted April 16, 2012 Share Posted April 16, 2012 You can use a PU adhesive (SikaFlex, Tiger Seal etc...) to seal it. It's used primarily as a body seal on vehicles but has the advantage that it's "passive" if/when it comes in contact with fuels. Probably best not to use it as a gasket sealant if you ever want to remove the sender but you can use it on the outside with the sender in place. DO NOT USE ANY FORM OF SILICONE/RTV SEALANT NEAR FUEL SYSTEMS. Silicon/RTV sealants will react really badly when they come into contact with fuel. They form a jelly in the fuel that clogs filters and even the smallest contamination can take ages to clear out. Quote Link to comment Share on other sites More sharing options...
Jiminy Cricket Posted April 17, 2012 Author Share Posted April 17, 2012 Dave, Thanks for the response. Will not be using any RTV then,..,.. Western - thanks for sorting my title Quote Link to comment Share on other sites More sharing options...
Tetsu0san Posted April 17, 2012 Share Posted April 17, 2012 If it's new then can't you return it? I thought they had a 2 year warranty on all products nowadays? Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted April 17, 2012 Share Posted April 17, 2012 What Tetsu0san said - I've already had one refund under the guarantee. Most sealants are not suitable for constant immersion in fuel, Loctite 574 will live with it. Quote Link to comment Share on other sites More sharing options...
