So I went in to do the cam tensioner. It had a manual unit installed before and was rattling.

After installation the new honda cam tensioner I have a question regarding the throttle body tubing area since my diagram is no longer on the intake plastic.

Here are 4 pics of the tubes.

7,8,9,10 tubes go straight to the gas tank ports.

Do 4 and 5 tubes go to 1 and 2 plastic port blockers? Why did the engineers make it that way? They do nothing? Perhaps for the California model with evap can?

Where does 3 tube go? to the port labelled 6?

Just making sure I have all that right. Thanks.

 

yes. 4/5 goes into 1/2. #3 is the vacuum hose for the map sensor... hopefully someone knows where it goes. i wont be working on my bike till later this week. but i think it does go to #6. similar to your picture, on my bike, only the vacuum hoses 4 and 5 have clamps..

 

The map sensor tube goes to #6. Next time u might want to remove the MAP sensor end, it is easier to reattach.

 

can you guys help me clarify if the tubes that i've circle red, go together?

 

4 and 5 are the hoses that you hookup in order to sync throttle bodies.

 

not 4 and 5. but the hose that i circled in red on both end. does that go from the Fuel Pressure Regulator to that vacuum line?

 

Checked last night for you. It does indeed. The red circles you posted do connect with that one line.
