Short answer is yes. Before removing the old one out (assuming itís not in 2 pieces), I tape one end of the old one to one end of the new one and just fish it on thru.

If the tape fails you can also use a wire coat hanger bent into a hook to pull it through. It isn't too difficult.

#2 is the part load breather hose. Itís a one piece hose with 3 connections. Connects at the left hand front of the valve cover (or cam cover), travels under the intake manifold to the elbow under the throttle body and to the evaporative emissions canister purge valve.

Were you able to get the hose replaced? I just did mine yesterday. It is a pain, but really just because of the difficulty getting the connector to release from the throttle body. I ended up getting a long skinny screwdriver in there and breaking the little latching ring off the old connector, figuring I was tossing it in the trash anyway. The new hose threaded in from the front with a little coaxing to get it over and past the obstructing stuff under the manifold. The only things I needed to disconnect were the 3 electrical connections near where the T-fitting goes into the throttle body. Nothing else needs to be removed -- not even the vacuum line. Total 10-minute job.
While you have it apart, you need to clean out the fitting in the cam cover where the PLB tube attaches. If this is clogged it can cause all manner of grief with EVAP codes (ask me how I know this LOL). There was a TSB about this, that I learned about a week ago while chasing my tail with an EVAP code. Here is the web address to link to the pdf of the bulletin:

I did broke the connector thats under the throttle body I tried to pull out but it was difficult and wouldn't move I used long screwdriver then while trying to get it out I broke it .
I used thin cable like hanger to pull the hose from under the manifold because the connector stuck and hit the knock sensor adjusting it here n there and pull it took about 15 minutes to install the new hose .

thanks for the link .
