Thank you Lozza , all sorted . Pingel is the the best option , due to size and flow rate . The original H2 vacuum taps are the best , but I put on bigger carbs and there is not enough room now between the outlet and the left carb.I was just spooked at the $420 option I found first on E bay . Now that I got the spelling right ,I found the right thing for half the price , thanks to Pokey .
