I've been slowly fixing small things on my buddy's 94 GT and one of the last problems I want to eliminate is an annoying raw gas odor that comes through the heater vents usually after the car is warmed up. Looking at a vacuum diagram I noticed a spliced line going to a vacuum reservoir as well as a speed control servo and "brake on/off switch... what the heck is that for? I know there must be a leak there as the brakes feel like they are losing power assist. A previous owner also removed all the egr stuff and I think they left a vent line open hence the gas smell. It looks like all this stuff is located in the fenders is there any trick to getting to them without removing the fenders? Car runs great btw no issues with performance.
