p2541
After a few hours of searching, I give up. 2009, Agency Power Headers, Eurocharged V7 E85 tune, 550 injectors. Under WOT, I get a pending p2541 code and I notice fuel pressure is dropping into the low 40psi range. I have it narrowed down to one of the two "fuel pumps" in the back of the car. Passenger side, being the double pump unit, or the drivers side "sending unit/filter/pressure sensor" all in one mechanism. Has anyone had this issue, or have any advice on which "pump" to replace?

Premature fuel pump failures are par for the course if you're running anything over E5... with E85 they are essentially wear and tear items. You better stock up on some fuel pumps.

Oh no, you’re going to trigger the rabid E85 squad by using facts.
