I'm trying to source the vacuum switch solenoid that controls the vacuum on the fuel pressure regulator. Online I can find the actual pressure regulator and I can find the fast idle solenoid, but I can't for the life of me find the vacuum switch .
Do any of the gurus out in Club Isuzu world know where I can source one. I was hopeful it as a fleabay item, but apparently not. Doesn't seem to appear on any of the aftermarket auto parts sites either, so maybe I'm searching for the wrong thing.
Engine is a 2.6L 4ZE1 in a 1995 Holden Rodeo Spacecab.
Thanks for any help you can offer.
