Suitable for any European fuel tank with 16mm x 1mm MALE petcock nipples, to my knowledge, which should cover most machines from '75-'86ish. (Early BMW guys please check, some use 18mm, which I cannot supply.) They will also fit very late Meriden Triumph. These are NEW parts, of modern materials for modern fuel. These petcocks have dual 8mm spigots, either to feed each carb or run a crossover. Made in ITALY.
Petcocks are identical opposites, levers operate in unison. Includes special LH/RH threaded nuts and sealing washers. Spigots are well suited for any tank with fittings on each side. Each petcock has circuits for main and reserve.
A little pricey, but the best you can get, period.
