Can Someone Identify These Unknown Parts?

[rebelz]

After the Engine Harness fire in 2015, it's taken three years to get the light at the end of the tunnel to change from those of an oncoming train to about a couple of days left to first start. I will post pictures of the damage, cause and some of the rebuild at a later date. For now, I have had my son in law help me quite a bit over the years and I found these parts on a shelf beside the Z. I don't recognize them as anything I took off. I'm not saying after so long I may have forgotten. Does anyone recognize these? I have looked through the FSM at pretty much everything we removed and replaced. Fuel sending unit and Plenum is all that is left. I also looked at the ZR-1 Parts PDF that used to circle the ZR-1 forums. I really don't know if they belong to the car. Believe it or not, the first picture is a view with the spring on its side the second is with it standing up. Any help will be appreciated. The car is a 1992.
