Is this multiport fuel injector spider supposed to look like this?
 

I bought a mpfi on ebay and the pictures don't have this steel plug in one of the fuel lines but it came like this. The steel plug wiggles a tad bit, but doesn't seem to come out. Should I yank this thing out with lots of force, or return it. Perhaps somebody has seen this before. I'd like to get my truck back on the road asap, but should I yank the plug or return it?

give it a shot. dont go crazy, but its not supposed to be there
