Speed inc. fuel rail fittings I know the size is 3/8 npt, but does anyone make a NPT fitting that dosen't flare? The fittings I have come across have a .020" rise in them, which dosent allow them to screw in but half way. I'd rather my adapters screw in all the way for a nice clean finish. Does anyone know of a straight 3/8 npt to -8an male/male adapter that dosen't flare?

Does this really look all that bad?
FAST has some with the O-ring fittings. I know there are others as well. I am pretty sure the price tag is higher on those BTW.
If thats what you want look around. They are made.

If you are turning the fittings in by hand realise you will be able to get a few more turns on them with a wrench.
All in all I say get what you want. But it still looks clean either way.

i didnt think about it until now, but my front two fittings are called '-8 90* full swivel seal hose ends' and they tightened up flush with the speed rails... and you dont need the 3/8 to -8 fitting in between with them. too bad they were like $25 each!
