Failing EKP
Did not start happening until after the LPFP install. It is that or the EKP. It occurs most of the time normal driving, not WOT.

Do you have any of the LPFP Socks for the factory pump in 535i F10? Mine got tossed when I put in the Walbro 450 and I used the sock from that install kit. I'd like to have the OEM sock and put factory pump in to diagnose.
