well just to frustrate me further, I just found another broken vacuum line (this time white) feeding into a valve which appears to go through the firewall to another valve.

Does anybody know where to find a complete vacuum line kit for our trucks?

 

Change them all dude, with rubber or they do have the black plastic too. All three solenoids get vacuum in and vacuum out to the component they control. The white one is for the a/c.

 

Yeah I have a full spool of rubber hose and an unopened box of fittings, and all my marking tape and looming, but I gotta figure out a) exactly where the smog pump goes, b) exactly what broke, and c) find a way to see what the hell I'm doing in a difficult place for me to even fit my arm.
I just gotta get an afternoon away from the wifey to clean my workshop and be inspired to actually finish once I've started. (My bay is a mess)

 

Oh yeah, never mentioned I finally finished the repair. Took about an hour and a half with my lil bro's help.
I was perched up straddling the block, he was my gofer.

Since most of the lines had already dry-rotted out, I was left more or less just the wire loom and just enough hoses left to hold it in place.
So yeah, the repair would take less than half an hour. But I'm an ocd bastard who can't leave well enough alone.

So I "ran" lines to measure and cut, and I took colored electrical tape and wrapped them with the corresponding color from the factory lines, bundled and zip-tied neatly behind the block, and ran new wire loom, and wrapped the length of it with electrical tape.

She still throws the cell about 15sec after I start her up, but she's getting 10-11 mpg again, which is what I got before I noticed the problem. Haven't run the codes since, but she's in desperate need of a tune-up which most of the other codes were before the repair.
