I am now at my wits end. Rotax deliver their engines in the USA fitted with AN oil and fuel connections and that is what my FWF kit comes with.
For the rest of the world Rotax deliver the engine with "metric" connections for the fuel pump, fuel rail and oil tank - which is what was delivered to me here in Australia.
Only problem is that no one seems to be able to tell me exactly what standard of "metric" Rotax uses. there is bound to be a European (or DIN) spec for what Rotax uses but I can't find any reference to it and the local hydraulic shops just stare blankly. Yes, they have a few fittings that screw on, but the bores are way too narrow and clearly not designed for one another.
Internet catalogues are no use without knowing the right specification.
This is starting to look like a nightmare. Adapters to AN may help in one or Two spots, but I am not a fan of adding an inch or so to overhangs at a pressurised joint.
The final solution may have to be to order spare parts, including a new fuel rail and fuel pump assembly if I can't identify a source of proven, specified metric fittings.
Yes, the local agent is aware of the problem, but so far no solution.
