So, you like live lines inside your interior eh? I would recommend either a copper line or stainless braided line and not a plastic one. Ok, is it a slant or small block?
small block, and yes electic senders are unreliable , i've had issues with them and the ones in the car now don't work so i am getteing rid of them and using gauges that i know work and are accurate. and i agree about the plastic line
