Adding a Fuel pressure gauge

I'm going to add the fuel pressure gauges to the long list and want to make sure I just screw the sending unit into the pre-fabbed chrome fuel line from Summit. Not a great pic of the fuel line but the socket bolt comes out and the sending unit goes in correct? I don't need another adapter to make it work. I bought the wrong stuff when trying to get the oil temp sending unit put together so trying to do it right the first time. I found this sending unit from Gaffrig which is where I will be getting my gauges. It has absolutely no info on it. I assume it's 1/8" NPT. Hoping someone else is using it and can confirm. Thanks again for the help.

Yes, allen screw comes out.

And Yup, 1/8th.

99.99999999999999999999% of all fuel psi senders and screw into fuel line gauges are.

I use permatex thread sealant. Just my favorite. That’s all.

Thanks SB, I placed the order.
