Fuel pressure low after blue spring update.

Got my truck put back together after egr delete and oil cooler. Installed the pressure regulator blue spring kit. When it fired up my fuel pressure was sitting at 70 psi. I ran it all Sunday afternoon and it hovered around 70 which I was happy about. Got up this morning for work and fired it up and now it's 50 psi. It's been 50 give or take a couple psi all day? Any ideas?

It sounds like your HFCM might be on it's way out. What was your fuel pressure before the Blue Spring upgrade? When were fuel filters last changed?

Fuel pressure was about 60 or so and my fuel filters probably wouldn't hurt to be changed. I mean it's pegged at 50 and doesn't fluctuate much at wot

Should be higher with the blue spring. Sounds like your HFCM is getting week...

Well that's great. Just spent almost 2 grand between fixing the air and deleting the egr/ oil cooler rebuild lol. Might as well throw it in too lol. How much does the factory hfcm run? Would it be reasonable to just upgrade fuel system or is that a big leap money wise?

Until you start to see it drop below 40psi under WOT, I wouldn't worry about it. Right now, you say it's maintaining 50psi even at WOT, which is still fine for your injectors. I think the HFCM is right around $500, but you might be able to find a used one for around $100 from folks that have gone to an aftermarket fuel setup. Unless you are going for all out speed, the stock fuel system is probably adequate.
