Installing a Glass Bowl Fuel Filter on my 1956 Chevy 150 

i have a 57 4 door 235 bel air in the same color. i eventually want to move my filter bowl away from the exhaust just to ease my mind. white teflon is okay, just dont want debris from teflon tape to gum up the needle and seat. good to make sure threads are cleaned and the tape is applied with none hanging over. yellow teflon is technically for gas. i use white teflon too because ive never had a problem as well. after i used the kind of flaring tool youve got, i retured it and bought a fancy flaring tool that fits in a vice and does a great job with little effort.
