Fuel pressure test port fitting.

Anybody know where I can get a fitting like this:

-4 Male to -4 Fem With 1/8" NPT Port Fitting PRE-60441 : eBay Motors (item 330376460040 end time Mar-11-10 12:23:08 PST)

But I want it to be threaded inside the male 4 AN part so I can reinstall the schraeder valve. I need the 1/8 NPT port for fuel pressure sender.

That one in the auction may actually be threaded like that, but it doesn't say, so I wouldn't bet on it.

I guess 4-AN is the size I actually need for the stock pressure test port. I have read that was the correct size in several places.
