Anyone know what the 5/32 vacuum line is that runs into the drivers side fender behind the ABS unit. Looking to replace the vac lines on 98 4.3, but this line appears to run down into the inner fender and may be pretty hard to replace.

Any suggestions?
thanks

It goes to the vacuum reservoir for the HVAC, cruise control and 4WD systems. The reservoir is just inside the left fender, near the hood hinge.
