Vacuum Leak Patched

I think I found one (perhaps the only one) of my engine’s vacuum leaks. I noticed that the rubber hose that runs from the fuel pressure regulator to the intake manifold showed cracking on it so I replaced it. It broke off at the FPR when I was removing the old hose and had to be scraped off with a knife. Now the car idles a little better but I (still) suspect my fuel injectors are fouled — so far the car is not stalling on cold start but does still idle low around ~500 RPM. Photo of the hose I replaced (see red arrows):

The inside of the old hose. Odd that the end closest to the regulator has a white buildup inside it, not sure what it means:

Part Numbers:

Hose: 11-72-7-545-323-BOE
