Fuel Pressure Guages

while taking a look online i noticed that mechanical Fuel Pressure Guages cost 20 bucks and electric cost around 250. Why?

Is there any way to put a mech fuel pressure inside the cabin or is it impossible?

It is possible, just use a longer -3 line to it, but the issue is you would have fuel flowing inside the cabin and thats not legal by NHRA, IHRA, most states laws and is pretty silly. You can find some nice electric gauges for around $150. Worth it? I think so, answers half the questions when a car wont start!

I'm not crazy about digital gauges, but yes, that gauge and sending unit for ~$105 should work.

Only issue with the mechanical gauges with the cheaper sending units is that they are typically off by 0-15psi at higher fuel pressures. If your just looking to see if you have fuel pressure they work fine. If your running a dry nitrous kit and looking for fuel pressure to rise, its nice to have repeatablity.
