You can use steel brake lines for the external oil filter. You could get fancy and slide rubber hose on the outside of the brake line to make it look somewhat correct.
Personally I cannot stand to hear the warning buzzers on my work truck. I asked the dealer where it was so that I could kill it. The technician told me that it was imbedded in the gauge cluster.
I then asked if there happened to be an accidental firearm discharge inside the cab, say a 22 caliber, where would would it have to strike to hit it. He laughed nervously and casually, but with purpose slunk away. I then vacated the premises with similar purpose, so as to prevent possible confrontation with the authorities.
Some people can't take a joke.
