Would anyone know the id sizes of -8an and -6an fuel line? which would you use from the pump to the carb?

Thanks
Tom

-8AN = 1/2"

-6AN = 3/8"

Depends on the pump and carb fittings.

Thanks for the info.

FWIW. I run 1/2"/-8an from my tank all the way to my carb. It may be overkill but with a 540 I don't want any fuel restrictions! ;)
