Another item I picked up at Bendigo last month was a NOS right side ignition lead conduit with an earthing strap for a Ford Sidevalve/Flathead V8.

I assume it was for radio suppression as used on Ford military vehicles based on the number of earth straps used throughout many CMP's. By the length of it I would guess the end goes under a water pump bolt.

Just wondering why it was necessary in the first place as the bolts that hold it to the intake manifold would effectively earth it to the block anyway? Am I missing something about electricity?

Thsi is the second right side conduit I have with the identical earth strap so I assume it was not an ad-hoc modification.
