Hi there
Having difficulty finding this info - can anyone advise me as to the recommended system? I bought an EAC1284P fuel regulator, but it seems to have a vacuum connection which I haven't got. The ancient barrel design part on the bulkhead has a fuel in, fuel return and fuel to carb and I suspect it's u/s. Currently using 5/16 supply, 1/4 to carb and 1/4 to return.

Currently thinking of 5/16 from tank and to carb with 1/4 return with a variable restrictor and just put a Y connector on instead.

Thanks for reading this.
