I went out and took this picture of the fuel pumps and tried to look on top of either of them and all I could make out was "Genuine ...... Made in USA". I looked all around and under them with a small mirror and couldn't see any numbers. You might want to call the Cobra shop manager, Tony, at SAI or Bud in CSX parts. I looked at the facet-purolator website and it appears the FEP 59SV is what these are.
If you're running a Holley or similar carb, no regulator needed. They put out about 6 psi. I think these are -8 AN fittings on 3/8" ID line. No return line. Good luck.
