I've heard of people using Braided hose for long runs of wiring in the engine bay with a bulkhead fitting on the firewall instead of the plastic wiring looms, they say in case of fire or fluid spills it is safer.

Any word on this?

I've been on fire, trust me the last thing I was worried about was a few dollars worth of wiring.

My thoughts, too expensive & too heavy. I would rather let air surround my wiring for cooling. If it's all home runs & no half *** patches, I wouldn't worry about spills.

Amen to that one!!!
