Hi folks ,

can anyone confirm what thread size the connectos on the fuel lines in the engine bay are ? The ones that join the hard lines under the car to the flexi hoses. I'm going over to carbs, at least temporarily , and plan to use the return line as the carb feed.

Thanks in advance

Yes!! The supply line is M16 x 1.5, return is M14 x 1.5.

If you're looking for AN adapters (as opposed to just running more hard line), the company Fragola makes them, though I dunno if they're available over there in Europe, part #'s are 491970-BL and 491971-BL to mate to -6 AN fittings.

But EFI is sooooo much better...

Thanks for that . I may well end up going over to EFI down the line. The carb setup will however at this point alow me to move the car about and get it driving again .
