Does anyone know an insulated starter wire firewall pass through whereby you attach it to the firewall then you can bolt the wire from the starter selenoid on one side of the firewall and then a separate wire from this "bolt" on the engine side to the starter. Does anyone on the list know if such a thing exists?
These are known as cord caps. You can get them in aluminium (as good as the fuel bulkhead fittings). basically they provide an insulated (rubber doughnut) pass thru of the firewall. You can then use some firewall sealant to cover the little bit of exposed rubber.
This would be more fire resistant than the nylon block/stud I think.
i used them in place of the eyeball vents for the cable pass thus...Look professional.
