Hpfp question

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?

Not sure where the problem is, but its on the high pressure rail

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.

 

Yes I do. Vcds.

Check your getting the right pressure from the hpfp.

Can that cause a code for all four injectors?
