ridelimousin Posted October 10, 2014 Report Share Posted October 10, 2014 Hi my fuel is leaking from where the tap enters the tank, I'm guessing the fuel tap seals have perished, does anyone know where these seals can be bought or if I may need a new tap instead? Thanks Quote Link to comment Share on other sites More sharing options...
tail Posted October 10, 2014 Report Share Posted October 10, 2014 Surely its just an o-ring 1 Quote Link to comment Share on other sites More sharing options...
ridelimousin Posted October 11, 2014 Author Report Share Posted October 11, 2014 I've now opened the tap up and there are 2 washers in there, one is rubber and one is a hard grey "plastic". Would it be ok to replace these with 2 generic rubber o-rings? I was thinking of getting one of these kits and looking for similair dimensions: http://www.ebay.co.uk/itm/225pc-Rubber-O-Ring-seals-Tap-Washers-Gasket-Assortment-plumbing-petrol-diesel-/141211297303?pt=UK_DIY_Material_Nails_Fixing_MJ&hash=item20e0d96617 Cheers.

crazybond700 Posted October 11, 2014 Report Share Posted October 11, 2014 If it doesn't leak it should be enough right? Quote Link to comment Share on other sites More sharing options...
thats_a_five Posted October 12, 2014 Report Share Posted October 12, 2014 Replace the rubber o-ring and reuse the plastic ring unless it shows damage. Replacing both pieces with two o-rings will not give a good seal. 1 Quote Link to comment Share on other sites More sharing options...
ridelimousin Posted October 17, 2014 Author Report Share Posted October 17, 2014 Well I changed the o-ring and after reassembly it still leaks. On closer examination it turns out the weld around the tap on the tank has failed, a tiny 2 mm long crack. I have chemical metalled all around the weld to completely cover it, waiting for it to go off now to see if it still leaks. Have had great success in the past with chemical metal one to repair a steel tank that was leaking from rust and once to repair an engine casing that had a hole from a rock.

crazybond700 Posted October 18, 2014 Report Share Posted October 18, 2014 Otherwise a thank is weldable (do water it first though!) 1 Quote Link to comment Share on other sites More sharing options...
ridelimousin Posted October 21, 2014 Author Report Share Posted October 21, 2014 Just an update: the chemical metal seems to be working well, its just the generic stuff that comes in a roll that you knead together. If it fails at some point I will get it welded but this seems fine for now, perhaps a permanent repair! Quote Link to comment Share on other sites More sharing options...
