fuel pressure gauge

running olds 455 with mechanical fuel pump. which fuel pressure gauge works the best...liquid filled or dry. and does mounting under the hood makes a difference.

I like the dry gauges and any gauge under hood is bound to fail. Vibration and heat is never good for a gauge.

I like the dry gauges the liquids I have used give false readings when used under the hood once the heat starts to build up
