Occasionalky hpfp fails on petrol, we have a lot of people on e85 long term here no noticable increase in hpfp or any other tupe of failure on E85 86/brz
I dont know about wrx dit, maybe as a single direct only fuel system it having to run very hard to supply the extra fuel ( maybe the dit tuners are increasing the di pump pressure targets )where as our cars with port and direct systems it not pushed as hard but thars just wild guess.
