I was told by NHRA tech years ago that they didn't, won't, allow plastic pressures lines on oil or fuel gauges.
I have used a 1/4 inch I.D. oil pressure line and it does make a large difference on the oil pressure gauge responding time , NHRA made me change that back to the smaller 1/8 inch tubing also
Their thinking was if it broke during a run it would put a lot more oil on the track during a run
