I havenŽt decided on the feed line. Was thinking -4AN though, but -3AN it will be then!

cheers for that!

Re: Is this a restrictor?

Just for sake of completeness. AN Stands for Airforce Navy. the AN size is derived by multiplying the nominal (internal?) size of a hose by -16. So 1/2" hose equals 1/2"*(-16)=-8AN

so in my particular case -3AN equals a hose with internal diameter of 3/16"=0.1875"=4.7625mm

anybody can confirm?
cheers,
david

So it's a pointlessly complicated way of measuring something in 16ths of an inch?

I can't see the application of MIL standards to automotive.

Re: Is this a restrictor?

this is why you guys need to fully adopt the metric system.

i'm not anti-imperial or anything, but metric is soooooooo much easier to work with.
