Re: How about some pics of 4WD 88-98 Trucks
I hear ya. Yea that's the fresh air tube for the air cleaner/pcv system. The pcv sucks out into the front of the tbi and that tube allows filtered air to enter the valve cover thru the tube. Mines removed, and I just bought a breather cap to run in my valve covers when I switch to the chrome ones. I plan to leave my pcv in though and use the breather to filter the air coming into the motor.
