The reason the fuel selector is hard to move is the parts are on a taper , and well machines.

Only a slight pressure is required to sieze a good taper , ask any lathe operator.

By loosening the packing nut and giving the shaft a slight tap to the shaft , the taper should release.

IF you do R&R the valve , take it apart to see if there actually was anything wrong with it.

I would bet a dollar to a donut hole its fine, was just well built.
Same on my boat, eventually they get stuck. All of mine are single in and out, all I need do is wedge n a pier of needle nose pliers or a small claw and pop them up, that pulls the tapers apart and it works again.

If it needs replacing:

Looking at the bottom photo, I'd say the fittings with the blue thread sealant are NPT on the valve side and a parallel threads (possibly JIC) on the outer side. Don't begin by unscrewing this. I'd wager that if you loosen the parallel threaded nut anticlockwise (looking towards the valve), you'll find it screws off the valve and JIC fitting without twisting the hose.
If its very tight, you may need a second wrench to stop the NPT fitting from turning in the valve, but once it breaks loose, it should turn easily. (like a hydraulic fitting)

Thanks for all the advice guys. Iíll try FFís approach first to see if I can loosen it.

Iím going to try this by loosening the packing nut 1/4 turn. Please clarify ďslight tap...Ē I donít want to bugger it up.

I think FF is referring to the fact that some tapered cone valves have a shaft that extends beyond the narrow end of the valve with a nut on it. You can loosen that type of valve by loosening the nut and tapping on the end of the shaft.

You canít do that as Anderson Brass fuel valves do not have this shaft. The narrow end is closed. One less place to leak.

You can only work from the packing nut end.

A tap is made with the hammer handle , not the head.


A 1/4 turn of the packing nut will not give much freedom , a couple of turns , but leaving the nut on should work.

Fuel tank selector valve.

That ďpacking nutĒ is actually cast as part of the faceplate of the valve.

Not sure if that changes anything. The unlike the Groco valve which is serviceable, according to Anderson, this one is not. Still. Iím willing to give it a try, but only just before and when Iím completely ready to do the full remove and replace.

If this works, I guess Iíll have a spare $400 valve!

Edit: the shaft has a slight bit of motion to it.

"That “packing nut” is actually cast as part of the faceplate of the valve."

Perhaps it is removable so the internal plug can be R&R?

It looks like it will unscrew from top of the valve.

Otherwise why would the nut surfaces be machined to a wrench size ?

Fuel tank selector valve.

Ok, so I drafted my son Eric the small engine-largish engine mechanic for his assistance. Actually he did everything. Heís quite familiar with these sorts of hydraulic fittings. First, we tried FFís suggestion to loosen the packing nut and free up the valve with a couple of firm taps. It freed up ok, but it weeped diesel. Ron at Anderson brass indicated this was a likely outcome. We felt it would only get worse so we went ahead with the valve replacement. Eric had everything off in 45 minutes and the new valve in and assembled in 30 minutes. We used plugs to keep the diesel in. Actually very little diesel was lost, easily wiped up with a few absorbent pads. No leaks at all after installation. I was surprised how smoothly it all went. Best of all I got to watch!

As I mentioned this valve is redundant as the supply and return lines have valves at each tank. Iím going to switch the valve to select for both tanks and control which tanks are used by opening and closing the valves at the tanks. That way if the valve freezes, it wonít affect the operation.

Yes, we did. As tight as it would permit. Eric felt as we had the new valve we should proceed with replacement. He was confident of being able to work with the lines, which was my fear about the process.

Now that you have the valve out , it should be EZ to take it apart and see what was causing the leak.


If its just an old O ring or something similar , post the results so folks can cure their stuck or leaking valve for a buck or two, rather than go full replacement.
