Wrong fuel pressure tester

[Jordan325iC]

I bought a fuel pressure tester from an autozone the other day, but once I got home I could not figure out how I would get it to work with my fuel setup. Here's the tester:

Seeing how I just spent $40, is there any way to make this work?

Or, does anyone know where I can buy the correct fuel tester that you can just "T" into the fuel line?

You are going to have to add a T-fitting into your current fuel line to be able to use any type of gauge.

So could I just get a T fitting and use this gauge?

You'll need a Brass tee fitting with 2 hose barbs on it, then an adapter to what ever type fitting is on that guage(can't tell by the photo). What I've done before myself is just buy an 1/8npt pressure gauge that will thread right into a brass tee and fit it inline on the high pressure line.
