Faulty oil pressure sending units, any input?

[Steve2000GT]

I was searcing on google and come across this. Exact thing my oil pressure gauge seems to do. On cold start ups will drop to 0 and then jump right back up to normal, and will do this a few times. Will only do it in the morning, never throughout the day. Thinking it could be this. Any experience / input ? Going to go to Ford and pick up this part 1U5Z-9278-DA which I guess is the revised oil pressure sending unit. I have a 2000 GT
