Sorry if this has been answered, I've searched and searched and have gone through a lot of threads.

If I am using the under hood fuse block that came with the 5.3 in my swap, do I run the grey wire from C3-F1 (fuel pump power) straight to my fuel pump of does it need to go to a relay first? I think it already goes through a relay on the block but I'm not 100%.

Thanks to everyone for all the info that is out there.
