Best manner to mount oil pressure sensor, Mine broke off Options

[HansJan]

So I suddenly lost all oil pressure doing 70 on the freeway.
After pulling of at next exit I find that the tube to the pressure sensor has broken off and let all oil spray out (no oil left in the engine).

At the moment I have to find a way to get the remaining piece of pipe out of the engine block, without dropping brass chips in the block.

I could then get another brass tube and reinstate it. However, it might be better to come with a way where the oil tube is not also responsible for keeping the sensor in place.

I’m thinking of making a short hose of some kind and creating a mounting bracket to the sensor somehow.
Would you be so kind to show me your solution?

A fixed mount like that is a recipe for disaster. Better off with a flexible hose. The argument is thread size. I can't remember, but grease gun hoses (1/8" PT) have been forced in, and some paintball gun hoses come in a metric size.
Since you already have the brass to the pressure port, an 1/8 PT should work.

I disagree.

I have successfully used hard lines for plumbing the oil pressure sender for years, but I don't ever make it that tall. The line will work harden from vibration and eventually crack and break. If you want to use a hard line, make sure it is as short as possible so the sender sits against the engine tin, then put a large padded clamp around the sender and anchor it to the tin. That won't work harden and break.

For what it's worth, the only failure I ever had was from a flexible line installed to hook up the oil sender.
