Hi Guys
Doing some remedial work on the blue efi
Next on the hit parade is to check / change the air filter
I can see how to remove tmthe tank etc fairly straightforwards
But a question
When im going to disconnect rhe fuel in and return lines will there be soillage and if so will i need to put a recipient on both lines to catch the fuel
Or is it minimal spillage?
Thanks paul

I'm doing the same thing next week and I was expecting to drain the tank.

I did see a post on here where someone had fitted a quick release to the fuel line, but I'm struggling to find the post and the correct parts at the moment.

Start the project with an empty tank, then siphon the rest out, although I'm not sure that's actually necessary. The remaining fuel is under pressure. Release it and the fuel thru the small bolt at the tank/fuel line. Yes, there is a little bit in there. Book says replace sealing washers. I didn't, no issues.

Thanks both for the replies So to fill in the gaps i dont need to expect fuel peeing all over the place right?
Ive spotted the pressure release bolt but its not been run since 2 weeks ao i guess its at ambient pressure

If you're only doing the airfilter (but maybe I'm missing something) there is no need to remove/disconnect the tank.
Just lift it and support it while you do the filter.

The spanner and the little oval tube thing from the tool kit (if you still have it) can be used together to securely support the tank.

I think you're right and that's all you need for the air filter. I'd like to check the valve clearance and spark plugs too so I guess I'll need to take the tank off.

You need to drain the tank as much as possible. I pull the FPR return line. Pinch the line about 2 inches back. Then work it off the FPR. Make sure you have a fuel can that can reach the line once it's pulled. Once you have the line pointed in the can uncrimp it. This will drain about 95% if the fuel. If your careful you can set the back on a 2x4 and level the tank a bit more. Be advised your still going to have some fuel in the line so put a rag under the fitting on the end of the rail. Be careful once it's drained as well there will still be some residual in the tank that will leak out at the most inappropriate moment trust me.

You can pull the tank or take out the rear bolts. Slide the front of the tank out of the mounts. The pull the metal liners out of the rear mount holes. Put the bolts back in through the now larger rubber grommets. Screw the bolts down about an inch at least the use a large piece of pvc pipe to support the front of the tank propped up. That should give you a lot of room to work once you pull the airbox.

Like Tappas said, no need to remove tank.Propping it up from the back doesn't give you the clearance. Prop it up from the front, I use a rubber mallet, but best to use a strap ( I use a standard tie down) from the front locating knobs to the anywhere at the back near the seat lock.
I keep saying one of these days I'm going to shape a piece of wood to do that job....

Partsguy is correct. The tank can be rolled so the back is in the "hole" behind the air filter and the front straight up without disconnecting the fuel lines. I did this a few times with the front tied to the ceiling for support. I didn't mention it because this stress caused the fuel line to spring a leak.

Like as been said above a lighter tank is easier to handle so less fuel is best.
No need to remove it, just remove the two retaining bolts and lift it from the front and just prop it with something.
I can change the air filter in around ten minutes start to finish.

Sorry should have added no spillage at all as you have no need to do anything with the fuel lines.

Quick release on mine. Tank off in two mins. Much easier but use a proper quick release on the pressure side. The plastic ones will pass.

From here. Tom Parker Ltd, Pneumatic, Hydraulic & Fluid Power Specialists | Home.
You'll have to drill down to find them.
About £45.00. The Viton rings do wear after a while and leak. Got a source here to get them from cheap.
Also use a slight smear if red rubber grease when connecting up.
It's worth spending the money on decent kit. Don't want fuel spilling all over a hot engine whilst blasting down the road (at no more than 70mph obviously).

Think that can be a project for next week along with a full service whist the tank is off.
