That’s what I figured, but are they enough for the pressure to drop down to...or below...45psi with a good running stock pump?
Bismic has SRL+ (and I’d assume FICM tuning), but only drops to 50 at full throttle.
Soooo...is my gauge reading correctly? Is my new Racor fuel pump flowing less volume than the 300k mile pump I pulled out? Are the seals in the pressure regulator bad? Is the foot in my tank breaking apart? Will I actually have the discipline to go trail running today in the cold?
A lot of questions need to be answered... 😉

For now the easy stuff- trail run today...maybe...then blue spring replacement, then get a good fuel gauge to compare. Then dig deeper...maybe.
That’s interesting that yours could barely keep up with minor mods...does that mean pretty much just tunes? Thanks for that info, makes me feel slightly less bad about mine 😉
