Default Fuel filter replacement

Replaced my fuel filter last night. Pressure before was 62-58psi from idle to WOT. Not sure when it had ever been replaced possibly when the blower was put on 12-15k ago, it was a GM filter. Put a WIX unit on last night and fired it up this morning. Showing 68-70@ idle and down to about 68-64psi 1/2-3/4 throttle. Normal or possible bad regulator? Previously Dirty filter causing lower numbers? Car has 60lbs injectors....

Seems like a nominal change to me. If the car runs fine, I wouldn’t worry about it.

That's what I see with my Wix filters. Nothing to worry about.

Whew! I figured it would be ok. Better to run a little rich then lean with a blower.
