This literally took me 2 hours to do.
This MAF/F-boot hose was TOTALLY baked on.
Petrified. I had to HACK away at it with a utility knife.
If was a very awkward position, as your hand can barely get in there.
Also, this was actually slightly dangerous, as I could have EASILY sliced my hand or fingers open.
It was EXACTLY like trying sharpen a pencil with a pocketknife. What a nightmare.
I was very tempted to just cut off the top of the plastic tube I was trying to clean off with wire cutters,
but I didn't want to pinch or crack the plastic tube I was connecting this vacuum hose onto.
At least an hour on this, and look at the sh*tty hack job I ended up with. I didn't even get all of the old hose off.
There was NO WAY the rest of the hose was coming off with that awkward angle for my hands.
This job was really idiotic to do, in hindsight.
There was nothing wrong. I sucked on the hose, and there was suction & no leak.
All my tugging and yanking trying to scrape the sh*t off risked more rupture/damage than a decade of exposure to any engine heat.
And I have NO idea where that plastic hose goes to. Somewhere down into oblivious in the engine bay.
Next, I was trying to replace the 2 intake vacuum hoses. (the two #4's)
I got the one attached to the SAP valve replaced.
But, I'm not even sure the size is correct.
RealOEM states 3.3mm = .129 so I got 1/8" (.125)
This doesn't look only .004 mm's different, however.
Unless the outside is just wider b/c of age and hardening to shape.
I was not able to find the 2nd hose.
I have no idea where this plastic tube goes....
Anyone have any clue where this red hose actually is???
That #3 appeared to wrap around the entire engine, and the disappear in the back.
I only found the plastic tubing below. Is this still #3 going all the way around back of the engine? (Not like the realOEM diagram)
This is the view from the passenger side of the engine bay
From the driver's side of the engine bay, standing above the airbox.
Where is the red hose !?!?
