I was looking at DD's fuel hose diagram on PP and don't understand how the Fuel Pressure Regulator works.

The fuel flow goes through both fuel rails before it reaches the Fuel Pressure Regulator.

The fuel flow on this is correct? RIGHT. I assume it is GOSPEL.

How's it work in the system???????

by holding the high pressure created from the pump back. (over 29.5 p.s.i.). it bleeds off excess pressure back to tank

Thank you! That makes sense now!

I was thinking it regulated the fuel before it got to the fuel rails.

See the little arrows on the nice color diagram?

I did (see the arrows), that is why I asked. I didn't understand (flow direction) how it worked. The arrows weren't making sense to me until orange914 so kindly explained how the FPR worked in the system.

I never claim to be that smart, that is why I rely so heavily on this site!

That's why "Krusty" is so appropriate.
