Direct reading fuel and oil pressure gauges

[Mac Transtrum]

I need to run the tubing for the oil and fuel pressure gauges . I have seen copper tubing used with compression fittings , but would rather go with standard AN fittings and 1/4 versatube. Does anyone see an issue with using the larger tubing as it will have a restrictor fitting where it exits the engine to prevent large fuel or oil loss should a line fail? Any pro or con advice would be appreciated .
