FFS 5th injector
 

Last year I bought a used FFS system (MP62). It has that 5th injector installed (but never used) from FFS. The previous owner went with larger primaries instead, and just left it there.

So, this thing is stuck in the side of the manifold, just hanging there. Do I remove it, or leave it alone? If the vote is to get rid of it, how does it come out? Appears to be pressed in, but I don't want to bugger anything up taking it out. If I do get it out, what do I do about the hole?

Should the plug be tapped, or just pressed fit in? JB Weld in a tightly fitting plug? I have a lathe, so I can make a plug to fit, or I can go out and buy some sort of pipe plug.

Suggestions?

Its threaded into the manifold. Or at least that's how mine is.

So, should I take it out or just leave it?

Up to you. If you are not going to use it, that location is a good spot for a WI nozzle. If you want to plug it, contact Tom, i believe he has plugs.

Its not going to hurt anything if you leave it in place.

It should be threaded in. Is this a coldside kit?

Yes, coldside. Does the hotside even have the 5th injector setup?

Previous owner ditched the powercard, and went with MSPnP and larger injectors, so it's never been used.
