Yes, that's all. The two "pins".

What seems to be the problem? The rail won't stay in place? It wobbles?

looking in my FSM I see 2 bolts one on either end of the rails. I would assume that they are not tight or one or more of the injectors is not seated properly and is causing the rest to be off. I dont have a 4cyl though but i had the book near me and thought id give it a look. what do you mean by pins? i dont see those anywhere but again I have a v6.

There are also 2 black plastic washers on the studs, below and on top of the rail hold-down....

You can make them out in this pic (click for larger view)...just to the left/right of the center (of the three front/rear) intake manifold holes. It sounds like you left the washers/nuts off.

There are two bolts, correct? Have you torqued them to 14 ft/lbs? There will also be a fuel line that clamps on on the firewall side of the rail and a small vacuum line and a fuel line that bolts into the fuel rail with a brass washer and 33 ft/lbs of torque. I had a b***** of a time with this as well but my problem was ripping the small ring washers on the fuel injectors. If you haven't pulled them out of the rail they should be ok, unless the visible rubber looks deteriorated. If you do pull them and service them, be sure to apply gentle pressure and twist them back on carefully, or I guarentee you, you'll have to pull everything off and do it again because they'll leak with the smallest nick.

I don't know if I answered your question because I don't quite understand it. If you've threaded the bolts even just finger tight, the rail should be secure so long as the nozzles are lining up correctly into the holes.
