Haven't turned it for some considerable time and now find that I cannot turn the wheel on my Atkinson Tankmaster - the thread has no doubt corroded.
It's this type of valve -

I know that you turn it clockwise to close the valve (it's a left handed thread so when turned the wheel moves outwards, releases pressure on the pin, and so shuts off the oil) so that's what I've been doing. It won't turn anticlockwise either.
I've tried squirting in some WD40 but so far nothing (not surprising really as even with the straw I can't get the WD40 into the area that's really seized up).
Any tips please on how to free it up, or I am going to have to get my installer to replace the whole valve and gauge? I hope not.
Thanks.
Edit:
Also, due to the stuck valve wheel, should it be necessary for my fitter to completely replace the Tankmaster gauge does the oil tank need to be emptied first or is it possible to replace the old gauge with oil still in the tank? The tank is just under half full.
