Electrical vs. Mechanical Gauges

I will only use mechanical oil pressure gauges. Try one of each. Let the engine idle, then give it a couple blips of the throttle and watch how fast the mech gauge responds vs. electrical.

Thanks for the plumbing tip, redfastback. A braided line would give me peace of mind. I'll go that route if possible.

I can go either way with water temp, though.
