bothfeetdown Posted October 4, 2010 Report Share Posted October 4, 2010 Hi there hope someone can help I've just bought a tank seat unit for my 1973 Cota 247 that has the original fibreglass tank and not the separate aluminium tank. I got it to replace a leaking Ali tank and cover. Unfortunately, the 12mm petrol tap from the ali tank does not fit the fibreglass tank. The tap boss on the fibreglass tank appears to have a 16mm metric thread on it. Unfortunately, the tank came without a petrol tap and none of the usual firms can supply a 16mm petrol tap. Any ideas on what to do please? Quote Link to comment Share on other sites More sharing options...

woodbutcher Posted October 4, 2010 Report Share Posted October 4, 2010 try WWW.ORO2U.COM part no. 18-615 m16x1.0 Quote Link to comment Share on other sites More sharing options...
bothfeetdown Posted October 4, 2010 Author Report Share Posted October 4, 2010 (edited) Thanks, but that's a female nut that screws onto an M16 thread, I need a M16 male thread one that screws in. Unless I can screw an M16 threaded tube into the boss on the tank and then fit that tap to it? I've tried Sandiford and Bultacouk/Inmotion with no luck.

charliechitlins Posted November 23, 2010 Report Share Posted November 23, 2010 While we're on the subject....I need one. I have the readily-available OMG one, but it took a dump after a couple years. The seal went. Probably old rubber meets new gas. Anybody have a suggestion for a replacement? Quote Link to comment Share on other sites More sharing options...
