BEGI 2025 FPR What hose goes where?!
 

Hi,
Almost done with my home brew FI and just need this BEGI 2025 fuel pressure regulator fitting. Ive bought it second hand and would just like to know which hose gets plugged into where?

I have labelled each hose 1-4.

Any advice would be much appreciated!

There should be an inlet and outlet. the inlet is typically the offset fitting, the outlet is the center...they should be labeled. The hose from the FPR outlet will go into the FMU Inlet and then out back to the hardline.

For the vacuum hose, tee off the stock FPR and then the needle valve fitting should have a check valve attached and it vents to the atmosphere, it should be able to bleed boost out but not let vacuum in.

Ok, thanks for the reply. So the inlet hose on the FMU is connected to the stock FPR (correct?) Then the outlet hose on the FMU is connected to the hardline....is the hardline what was previously attached to the stock FPR(correct?) Sorry for being slow!

When you say tee off the Stock FPR, do you mean blank it off and seal it?Which end? So is the vacuum hose (no.2 pipe) connected into manifold or into the stock FPR?

The check valve...so thats not connected to anything and just left to vent off?

Thanks again!

use a T hose fitting and grab vacuum from stock FPR, it's the vacuum hose that connects from ur stock FPR to intake manifold, cut it and fit the T fitting and grab vacuum source from there.

yes check valve should be left unconnected to any vacuum source, just let it sit in your engine bay
