Tapping FD primary fuel rail

[gonzoninja]

I\'m looking to tap the primary fuel rail mainly to remove the fuel pulsation dampers, but also so I can put better fittings in my fuelling system.

The fuel lines will be -6 JIC but what size should the metric side be? I\'ve seen some stuff about an FC fuel rail where they use an M12 fitting on the FPD side but an M14 on the other side.

handy pic half way down but NPT might be a bit hard to get taps for.

ooooh good find :Thumbs-up

so 3/8" BSPP should work then and that shouldn\'t be too tricky to get a tap for
