Where is the EFI relay?

2008 with 5.7L. This diagram is from Chilton manual. Where is the EFI relay? It's in the gray area. What does that mean?

 

Guessing in the e-box under the hood

 

Also looking for this answer

 

I am looking for the EFI relay location too.
Can anyone point me to the right relay?

 

It must be in the fuse box look there. That's were the relays are located for the most part.

Thanks baraynavab, but it is just not labeled. In fact there is nothing on the relays that remotely sounds like it could be the EFI no 2 relay.
I'm sure I'm not the only one not being able to find it. The video was helpful though.

 

I may be mistaken but I believe it's in the frame rail adjacent the fuel tank.

There was a thread a few months back I posted in where a member was repeatedly popping the pump fuse. There is a circuit back there in the frame, left side and I'm sure the relay is there.
