Vfr 800 Fi Fuel Lines / Lower Air Box Questions

Hi guys-
I installed a new (to me) fuel tank onto my VFR the other night, but the return line was in rough shape - at lest the outer layer. I bought some Gates FI hose from the local auto store, but getting to the fuel rail looks near impossible! It looked like I would have to remove the complete air box (lower too). I removed the velocity stacks and the screw up at the front right, but there seems to be more (much more?) holding it in place. My fist question is: Do I even need to remove the air box? And if so, how does it come off? Any pictures would be great if you have them. Take care,

About the need to remove the lower portion of the airbox to replace that line...i don't exactly recall, but you should be able to tell just by looking since you have the top of the air box off.  And yes, removing that lower portion is the biggest pain of anything on that bike. There are a couple of electrical connections that are kinda under the box that are hard to get to. There are also hoses under that box that need disconnection that will "hold" that box down.  With the stacks removed and the front bolt removed you should be able to lift it very slightly, now you need to look closely under and all round that box for whatever is holding it, there really is a lot of stuff connected that is difficult to get at that has to be disconnected, removed, You've got pair air connections, vacuum tubes, iat sensor connections, solenoid control valve connections etc. Work and check around/under all four sides, you gotta kinda keep somewhat forcing it upwards as you keep removing stuff to give you more room to get at even more stuff. Then of course when reconnecting make sure to double check cause some of those connections are under the box and you will never actually SEE if you have them connected once the lower portion is on, just be careful, take your time and make sure every connection you removed is reconnected. It is absolutely a pain as there is little room to get your grubby mitts under/around the box to work.

And yes, removing that lower portion is the biggest pain of anything on that bike.

You gotta be kidding me.  There's a laundry list of things on the VFR that are harder to do than remove the air box.  It's a piece of cake, you just have to read the service manual if you've never done it before.

Well, I personally have done valve adjustment, brakes, forks & seals, chain, rear suspension - and I think those things are much more straight forward.  JMHO.

Maybe its just me....but I have disassembled about everything on a 5th gen VFR including swapping engines, and the task i hate is removing that lower airbox, yup i've done it a number of times and know where all the stuff is, it is still a pain for me. Removing cams for underbucket shimming is far easier for me than getting that lower airbox off.

Mind. Blown.

It's that air injection valve below the front of the airbox PN 36450-MBG-003. It has hoses to both valve covers and the airbox. Perhaps its use is restricted to the CA models, but I agree with my fellow west coasters,,,wrestling with that sucker is not fun.

I'm thinking that removal of the PAIR system would make lower airbox removal easier going forward.  PAIR system removal and block-off plate installation can be done without lower airbox removal (I did it), but it isn't easy.  Space is tight.
