Hello, new here with a (newly acquired) '58 F100 272 Y-block.
I'm puzzled at some of the findings tho- I hope someone here can perhaps shed some light.
I found a three prong plug sticking out from under the hood and chased it to this small canister and hoses? Anyone know what this stuff is?...or what it should be?

The plug



Traced back to this on the right side fenderwell. The plug wire goes into the lower portion of this small upright canister



Overall, you can see the hoses...one plugged, etc
