You could probably get by with -4 fittings, although if I recall correctly they were significantly more expensive and had less range than -5 and -6 fittings, so personally I wouldn't bother buying AN fittings in that size for fuel.
Would like to know if i use -4 AN fittings and lines for FPR ; is it too small for NA Application? (16v 4AGE, running 210cc injectors)
is it gonna restrict the fuel flow ?

i didn't knw that man ... i got hold to heaps of -4 fittings and lines for free. so wana make sure they okay for my set-up.
Just cause you got them for free is not a good enough reason to use them. You could always sell them and buy a better size.
