Default What needs to be earthed?

Starting to look at some of the smaller detail items on the “to do” list for my 289FIA replica build.

Any detail descriptions and advice on items that need to be grounded/earthed would be much appreciated.

Relevant information that might be different to the average build:
• The chassis is a semi-monocoque unit that is all aluminium alloy, not mild steel

Here are some of the items that I’m aware of that would probably need attention, but feel free to expand further (I’ve not built a car almost from scratch previously)
• Fuel tank (mine’s aluminium alloy)
• Fuel filler (any detail I need to pay attention to?)
• Engine (302W, so cast iron) - needs earthing to alloy chassis?
• Gearbox (Toploader, also cast iron) -needs earthing to alloy chassis?
• Radiator (alum. Alloy) to alloy chassis
• Radiator ….Mg sacrificial anode on the cap, as well? Yes?
• Wiring? I'm a mech. eng. ....wiring is not my strong point

Anything else? A little care and attention now might well save wasted time and cash further down the track, so all comments welcome…

Thanks in advance.

Cheers!
Glen
