We bought #5721 Oil Pressure gauge that comes with plastic tubing. We want to change that to copper tubing. The copper tubing we have has a smaller opening than the plastic.. Will this work? Or does your #3224 copper tubing kit have a larger opening?

Asked by: MaryE
Narrow diameter tubing will not be an issue with this pressure gauge.
