Most aircraft have fuel pressure gauges... and fuel boost pumps. Part of the takeoff and landing checklist is check fuel pressure and turn on boost pumps.

If it wasn't critical, they probably wouldn't go to the time and expense to include these components in their systems. Our cars are not so critical as a fuel failure is generally an inconvenience rather than an emergency, but as has been pointed out, gauges can provide a wealth of information that can help identify problems before they strand us.

I'm not sure I'll install a dash gauge, but I probably will install a diagnostics port or a gauge in the engine bay.
