Fuel Pressure Fluctuates

[mark4g63t]

Having a fuel pressure problem where it goes crazy and bounces between 38 and close to 60 psi. Just pulled the AFPR it's an Aeromotive A1000 and it still looks new inside. Checked the return line and nothing blocked it as far as I could see.
Here's the video of what it's doing. (https://www.youtube.com/watch?v=_KOz_X5ImEU)
Thanks for all the help so far!

Another idea, maybe take off the feed line from the rail and put into a bucket, see if you are getting weird pulses of fuel instead of a constant flow. If you have the time, check another pump.

ok. I'll try that now. Thats a good idea.

I can blow through my return line no problem and it bubbles the tank. so it's not that
