Curios?????

I replaced the distributor in my 95 Chevy 1500, 350/5.7L. When I took it out, I noticed right behind it was what appears to be some sort of sensor w/a connector plugged into it. Does anyone know what that is?

Oil pressure sensor.

Thanks for the insight. I had no clue what that was.

While I'm in here I might as well ask this question. I installed a new fuel pump and sending unit in 95 Chevy 1500. There is a constant buzzing sound coming from the fuel tank even after I start the truck. Why is it doing that?

Probably just a loud fuel pump, I can hear my pump run on my 96 with the engine running

Thanks. I didn't know what was going on.
