You can buy isolated mechanical gauges: they are required by some auto racing class(not sure if it is autox, etc). I think the way they work is the fuel pressure pushes on a pressurized diafram, which then connects to your gauge. Either that or it has some sort of safety check value that won't allow [much] fuel to flow if disconnected. I'd go with electric, but make sure it advertises good response times, so you can visually see small spikes/dips.
