Fuel Pump Filter

So my bike is struggling a bit with fuel delivery, that or the gas over the winter didn't have enough stabilizer and went bad. I haven't gone through the entire tank yet since de-winterizing it, the bike runs but will shut off sometimes when idling low (Sometimes its fine and when it warms up/after riding a bit).

Anyways I wanted to remove the fuel pump and clean it up, clean out the filter. I wanted to know who has experience doing this, and whether I need to drain the gas tank first? Or is there a cut-off valve between the pump and the tank?

Also can anyone recommend some type of cleaner to remove the crud in there?

It's a K7 gsxr600
 
I think the pump/tank is similar to the hayabusa, I had to clean it out on my 06 a few times for a fuel delivery issue, it's not that hard.
I would run the tank low, prop it up and unbolt it, the fuel wont run out if you keep it upright. There will be a quick connects in the lines/wiring going to the tank. If the crud in the tank is rust, no cleaner will do anything, that's the issue I had. Pop it open and see what's doing.
 
I highly doubt it's a filter issue. I've had 2 gixxers with over 60k. Its probably the stabilizer.

If you still insist on removing the tank, use a small vise grip with some tubing slipped over the jaws. Clamp away & do your stuff.

If you wanto get ghetto just bend the bottom part of the hose & tape it
 
It's unfortunate there's no fuel drain valve on the gsxr or I would have done that first. Maybe I'll pick up a siphon on my lunch break.

Seafoam is supposed to be able to clean out bad gas though right, I could spray that into the fuel filter?
 
Seafoam is a fuel additive, and you already have an additive in the gasoline. Personally I'd ride out the tank of stale fuel before adding more chemical.

Once the Seafoam is in, I'd ride out that tank as well and fill with fresh fuel.

I don't think it has anything to do with filter or pump. I would just put 94 octane and go for nice highway run. You could check aftermarket fuel control component if you have one.
 
Lol, I'll just keep my input to myself in the future
 
Haha no I appreciate the input rockerguy. I'm going to pick up a siphon today just in case. The problem is I don't want to get stranded if I'm out too far. So far it's been fine, if it dies at a light I'll just give a lil rev while cranking to get going. I'm sure all of that is contributing to excess fuel though.

I haven't gone on highway since de-winterizing actually, maybe I should just ride somewhere far and gas up and come back. If that fails I'll siphon out as much as needed and check the fuel pump.

Thanks guys, I just didn't have this issue the last few seasons with the bike but maybe the fuel stabilizer I used is getting old and somehow contaminated (it did look a bit cloudy and dull).
