The fuel selector is the valve you use to switch between on, off and reserve.

In the center of that knob, that little black cap will pop out exposing a phillips head screw. You'll take that screw out, then remove the knob. Once the knob is off, that black plastic ring has a black plastic nut, under that knob you just pulled off. Remove it and the entire fuel selector valve can now be pulled out. Once you have it out, there should be a small screw on the side at that threaded area. That screw is what holds the plug valve in place. Remove that small retaining screw then take a pair of pliers and pull hard, the plug will pop out and you can clean the entire thing.......:cheers:
 
I realize this is an old post but it seemed worth resurrecting since it is a very good step by step instruction for cleaning the fuel selector switch.

One thing I learned the hard way is that once the stem or plug is removed, there is a rubber insert that is down inside the switch body (down in the area where the lines connect but inside it). That rubber insert can look like dirt but is not. Trying to clean it by scraping it with a small screwdriver will ruin it. The other rubber part is the O ring on the plug. It is worth inspecting that too.

Does anyone know if the rubber insert can be purchased rather than replacing the whole switch? The switch is the 275 500 089.
 
I just replaced mine. For $25 bucks it seemed like good insurance. Also, I didn't know that it could be disassembled down farther for cleaning. I may take the old one apart and clean it and keep it around for a spare.

Yep, removing the little Phillips head screw will let it come apart further. Be sure you pull out the rubber thingy that is inside the valve before soaking it or doing any aggressive cleaning. Its that rubber thingy that Id like to buy if it is available. If I can't then I'll do the same thing as you.
 
I think all 5/16" selectors (97 XP, 98-99 SPX, and all 951s) were not serviceable. Only 1/4" have a screw to disassemble.

One other thing on the 5/16" selector is the fittings. They are pressed in and if they spin at all its possible to get air bubbles. At the very least put some RTV on the fitting or replace. They break loose pretty easy so be careful.
 
Thanks guys. I suspect the rubber part is not available so I'll be replacing it.

A bummer that I took a fully functional valve, and "f"ed it up by thinking I should go the extra mile and clean it out better:)
 
So I installed the new fuel selector tonight, straight forward enough. One thing I did notice is that it moves very easily and hard stops at each end of its travel. I walked over to my 96 GTX just to compare and it needed a firm twist to turn and never seemed to hit the end of its travel. My guess is there is either gunk in the valve or the oring is dried out or bad. No second guessing this, I came right in and ordered a replacement. Last thing I want to do is hatch the motor on my new to me 90 hour GTX over $23 shipped!
