Since you have the new one, see what size deep well socket will fit over the top.....If you don't have one, get one or borrow one.

I know its a bugger to get at.....But, that's the way I've always done it.

Just tryed a 1 1/16 socket on the one I have in the garage.....Works like a champ....It looks round, but has serrations.

kind of a blurry picture but here it is. you cant really see i circled the nut i was talking about. id use a wrench but theres no way i can get to it with one, short of taking the whole engine out

A crows foot wrench may work. I have made them in different sizes from an old open end wrench. Cut the wrench off and weld a rod to the flat part of the wrench. Use vise grips to turn the rod or weld a handle on it.
Crows Foot...

Another option is to go to Home Depot and get a facet wrench. It will probably damage the round top, but may loosen it up.

I've never seen an oil pressure switch with a jam nut (I assume that's what you're describing). Pipe threads don't use nuts. Can't make anything of your photo either, except that it doesn't seem to be the oil pressure switch area. ??????

I don't know for sure that you will have enough room to get the facet wrench around the sender. It's a little bulkey. Just another idea. ???

think i might just opt for the crows foot. this is turning out to be quite the predicament.

This is a simular oil sender, with the hex under the body, but its for a gauge and not a indicator light. Do you have a gauge?

I have tried a sharp chiesel and hammer, tap it enough to loosen on the edge
Sounds like a last resort measure.....I'd be afraid of breaking it off in the block:eek:
