Hpfp question

[Donfero]

For the guys running stage 2, is the factory hpfp enough or did you upgrade. My car just will not give me a break! After fixing the low boost problem now im having low fuel pressure!!

Are you getting problems with the injectors because of the hpfp?

I know that hpfp’s can fail also cause low fuel pressure. Have you got vcds or obdeleven?

You need to upgrade the HPFP internals, I have Autotech upgrade.

Can that cause a code for all four injectors?
