They also brought up the WIX part #33737 in that post - the 99-04 corvette fuel filter/regulator that you can get from Rock Auto for $36. Anyone have experience with this? What is the regulated fuel pressure?

Here's the details I've found so far on the in and out sizes:
5/16" is return.
Russell PN 640863 is 5/16" to 6AN (for return)
Russell PN 640853 is 3/8" to 6AN (for inlet)
Russell PN 640940 is for 6AN outlet

The LSx is a 58 psi motor, correct? Does anyone know if the fuel pressure is 58 psi with this filter regulator?

I'm also concerned with this only being 3/8" in/out. I guess there's always the option of running two of these to match the flow capacity of a 1/2" line.

Anyone know some good info on this filter/regulator?
