Long story short i have two fuel rails both with 4 270cc dohc ka injectors. My problem is that one rail has cream color plastic nipples at the ends and one of them is broken like someone dropped the injector and the nipple cracked.

The second rail is similiar except instead of complete circles all four of the injectors have just a circle with 4 little pegs that dont really seem to do anything. On the peg rail i have one of those little pegs broken off. So what is the point of these little nipples on the end of the injectors.

I am assuming they are for sealing to the intake manifold. Would it be alright if i just mix and match the rail and have four unbroken nipples or what should i do. I can provide pics if necessary.

Edit: Here is a really good picture of what i mean. Top being the four peg and the bottom being the complete circle nipple.
