local hydraulic shop, most will carry aeroquip or parker fittings, some will even bend it for you
I used flex line ss aircraft hose and fittings from aeroquip.
if your doing the hutch fuel return mod
the passenger side forward head npt fitting is a bear to remove.
a 12 point socket 5/16 if i remember correctly on a universal helps tons.
i installed a 45 degree elbow back in which made teh line fitting stand at a 90 degree relation to teh engine and about a 45 to the heads. made hooking up easier.
and the rear drivers head, depending on which elbow you ues. it you will unbolt the turbo donut thingy near teh rear of the head it gives you much needed acces to teh rear plug
i dont have any newer pics. sorry
