I recently switched from TPI to a carb. The fuel supply, and return lines have the oddball fittings with the o-ring. I want to use AN fittings now, but I don't know what size the supply, and return lines are. Earl's sells adapters, but only in 2 sizes. 14mm x 1.5", and 16mm x 1.5". Does anyone know what size we have to use?

Thanks,

Maybe I should clarify. I know the size of the lines, but I don't know the size of the fittings.

Thanks,
