I am trying to replace a fuel pressure regulator on my 2000 Honda Accord LX 3.0 engine. I bought the correct FPR. However, I am looking for the location near the engine. 1999 had it on the rail, but in 2000 it may be in a separate box by the firewall. I want to change it myself and I am searching for the location.

Looks like it's on the fuel rail by the throttle body.
