where is psi port on filter housing

[mikeandmary]

Wondering if someone could point me in the right direction fairly quickly...

i'm coming down the homestretch on installing my chip, exhaust, and guages, but stuck on the fuel pressure guage. can someone tell me where the psi port is on the back of the fuel filter housing? i've done some searching and all i could find was mention of a test port that is an allen plug on a 6.0. is that what i'm looking for?

i've got glowshift guages, and they call for me to install into the psi port, but i cant find any mention of it anywhere. i know its on the firewall side, but it's pretty cramped and i can't quite see what i'm looking for

A quick answer would save the day for me here. Thanks in advance!

so one more question about this... What the heck do i need to get that plug out of there. I fiddled around with it for quite some time and tried every alan wrench i have. i thought i read somewhere that's what it was. i finally broke out the boroscope to get a good look at it, but from what i could see it looks like a round, recessed opening? Hopefully it's not rounded off from previous removal. if so, can i put a channel locks on the outer flange and get it moving?

hey man there are 2 port plugs you can choose from...if one is rounded you can use the other...one is pre-filter the other is post-filter. Here is a great website to learn about your fuel bowl.
