Hooking up Fuel Pressure Tester

[chesster6969]

I want to hook up a fuel pressure tester in order to test my pump's pressure. I dont have one yet and I saw that Kragen's has one for $50. My air/fuel gauge kinda runs on the lean side most of the time. I replaced the injectors with new 4-pintals, changed fuel pressure regulator, fuel filter, and all the rubber fuel hoses.
I changed the fuel filter when I bought the car since the pump was making a whining noise (filter was heavily clogged). I now believe the pump might not be working 100%. Is there any other tester gauge that I should look into or anywhere where I can rent one?
Im sure all I would need is a T fitting.
Also, anybody have any links,comments on how to approach this correctly?
Thanks

There was some Fuel pressure test kits on ebay with the T, and two hose nipples. And I believe they were cheaper then some other places. You can make one by buying a guage at any hardware store that is for watter pressure, then go find a T and two nipples for it.
