Hi
I have a 98 TBS.
I bought a pingel fuel valve and monza petrol cap from bellacorse.
www.bellacorse.com.
BCC-085 Polished Monza Fuel Cap
BCE-020 High Flow Fuel Tap
No surprise that the fuel cap fitted perfectly in about 5 mins but the Pingel was just as easy. No drilling required as the gauze filter is the correct diameter to fit into the tank. The kit comes with an adaptor that will fit the TBS tank. I didn't even have to drain the tank completely - just enough so I could lay it on its side (with the petrol just below the level of the filling hole) and remove the old POS fuel valve and replace it with the pingel.
Only extra thing needed is some teflon tape to wrap around the threads of the fuel valve before it is screwed into the adaptor plate. The tape I bought from a local DIY shop. Clear concise instructions so that even I could manage it.
Looks good, top quality product, easy to fit - no drilling, but best of all - no leaks!!
