Fuel pressure sending unit problem

Oil pressure sending unit problem

SORRY, LATE, TIRED: oil pressure NOT fuel pressure

Issue pertains to a Paxton Novi 1000 install but is specific to our model year:

-Oil pressure sending unit...all photos show it being on some sort of extension...well, mine is tight on the block. There is pretty much NO WAY to remove it because the "bolt/nut" part that I would turn with a wrench is too tight to the block and tons of things are in the way. That and the sender has broken off of the part that is threaded on. So, I guess I need a new sender...but how the hell do I get the old one off? And where would I find this "extension" I see the pressure sending unit on in both the Paxton installation manual and in an installation pic in a book for a oil pressure gauge?

Yeah, metal base is still there. I only had two adjustable wrenches and a smaller pair of pliers, so I'll add to my tool collection and buy something to get it off.

And yes, it was plastic topped, which is why it broke so easily.

Any clue on the size of the threading for the male and female ends of the pipe I'll be looking for? I'll take the Y fitting from the s/c assembly to make sure it all fits, but it would be nice to have an idea on the size to speed up the process.

Thanks.
