K&N to Stock Air Cleaner Reversion

When I bought my truck (2006 DC Limited), there was an aftermarket K&N cone setup that was a little too throaty for my liking.




I found a stock airbox at a local salvage yard and I am much happier with changing out the throwaway filters instead of cleaning the cone.



K&N has a good write up on how to install their products for our trucks in their website. The uninstallation is pretty much the reverse. Here are some pictures of my process to uninstall...




Cleaned the dust out...


unbolted the two standoffs...




Removed the bracket holding the K&N housing.


The third threaded bolt hole (nearest windshield wiper reservoir) did not have a standoff...



Installed salvaged airbox.

I attached the MAF and routed the cabling. There is a clip attached to the cabling that fits in the tube housing.



Attach crank vent hose, fuel pressure regulator vent hose, and power steering pressure switch vent hose.



A problem I encountered while trying to use the K&N supplied vent hoses....



The crank vent hose and fuel pressure regulator vent hose are too long. It makes sense, these hoses are meant for an aftermarket K&N kit, but I am having trouble finding the right OEM hose for the fuel pressure regulator vent hose. Could anyone point me in the right direction? I believe the crank vent hose is Toyota part no. 12262-0F021.



The only thing close to the fuel pressure regulator hose I could find was this (part no. 90999-92002):



Also, I had to order another hose clamp because the salvage unit only had one:



I would have used a regular hose clamp, but Toyota put a nipple on the tube and a hole in the clamp body to fit and grab better.

I hope this helps someone in the future.

You could always cut and re-use those existing hoses down to size if they are in good shape.

 

You're right, I could, but I want to preserve the existing hoses for reinstall in another vehicle. I believe they are just silicone hoses, but I wanted OEM hoses and be done with it.

 

Skinny hose search is not easy. Your pictured one looks like it may work, but data is conflicting.

 

I replaced my hoses, I took the old ones to a parts store and just matched them to the closest diameter of generic hose. Those are just vacuum lines, no reason to spend the big bucks on Toyota name there.
