Manifold pressure sensor part number

[Romeo-Victor]

So, my Manifold pressure sensor stopped workin. It was reading about 5”-7” low. When master was turned on it would rest between 23 and 25. I installed a mechanical only to have the needle bounce like crazy because of #3 cylinder intake fluctuations. The sensor I pulled out was installed by the builder and it has no part number or reference number. Only a DOM and “Made in Taiwan”. It has 4 wires. I would like to continue to use my electrical Vans gauge. What sensor is everyone using now??? The back of the gauge has 4 posts. +. - G. I.
What sensor can I use nowadays that it’s easily obtainable?

Thank you guys for any help.
