A note out there on filters from my personal race car.
Backstory: The car would start harder and go lean on any boost above 10psi. I logged fuel pressure and saw it dip. Knowing my injectors are clean, I replaced the fuel filter. This did not solve it.
Diagnosing pump area: findings were as shown in pictures. The fuel pump pre filter was clogged after 10k miles of e85
Reminder: check and maintain your filters
