Rattle from my LOBA hpfp

**slowone11** · 07-26-2016 08:57 PM

Anyone else have the Loba hpfp? Im getting a rattle between 2500rpm and 3500rpm no matter what gear or speed. After 3500 or before 2500...no rattle. Its weird. No power issues either. Its bugging me

maybe im wrong, but I thought those fp were only for the golfs, not the b8 a4s......maybe that's the issue?

Its been on for 12,000 miles. I had a shop order and install it so im hoping it is for my ride. Everything bolted up fine.

Little update on this issue. Talking with a couple of tuners and they belive that it is my injectors trying to keep up with the upgraded hpfp. I am still on stock injectors.

So, time to upgrade the injectors?

I'm having a really hard time trying to figure out how that could possibly be the case. Regardless of what rate the pump is flowing at, the fuel pressure regulator will limit that pressure, otherwise you would run way too rich after installing an upgraded HPFP...
