Update , I got another wix filter/regulator . After install it is at 60psi . The other I got was at 54psi . Thats 10% difference in pressure . Not a big deal on just an average swap with a stock fuel pump .

I started this thread to understand the filter/regulator and how it works . As it turns out check your fuel pressure if it is for performance use . Don't just trust what it is suppose to be .

We have confirmed the inlet is the 3/8 offset by the pictures . The internet is all over the place about which is inlet and return . I have come to understand this filter . I am going to tune with this filter and if not satisfied I will upgrade .
