So...I've got this full gasket set for my rebuild. NA FS-DE out of a Pro5, and I've got a little baggie here of O-Rings. I've ordered them in a picture from biggest to smallest, and I want to say the Biggest one is for the Oil Pickup tube, as it fits well into the recess in the bottom of the oil pump. There are four equal sized o-rings which are probably for the injectors. BUT there are two itty bitty little o-rings and two medium sized o-rings that I've been unable to identify. There's also this copper washer that i've been unable to identify. Might someone be so kind as to help me out?
