I just finished installing my TPI plenum and runners after swapping the gaskets. I have 1 extra torx bolt that I am confused about. Same bolt that is used to install the runners to the plenum. I’m sure that all bolts are installed everywhere. Is there a torx bolt used to clamp down the fuel lines from the fuel rail? It would be located just under the front of the intake. I am missing a bolt here and I’m thinking that perhaps that is where the torx bolt goes. I just don’t remember a torx bolt here. I'll have to remove the fuel line to find out so much help is appreciated here.

 

I think the fuel line bolt is a 14mm hex. (At least on mine). Did you remember the two torx bolts the cross under the plenum to the back of the runners? How long is the extra bolt?

 

I'm not sure of the length. It is the same as the Runner to plenum bolts. Its the short one. No I did remember the 2 in the back. You should have seen me hacking my runners before I saw those two bolts. I could have an extra one from a previous TPI unit that I sold. But I didn't think so. Just curious - Is the bolt the same for the clamp located under the Alternator (near where the rubbber lines meet)?
