So I'm looking at getting an electronic fuel pressure gauge for my truck. The two mounts I was looking at was the single column mount. The other style I was looking at was a dual guage cluster bezel (mounts by your regular spedo/tach/etc). I already have a triple pillar gauge set that has trans temp/pyro/boost. Is there another gauge that I should get too or just stick with the single fuel pressure gauge? I would get a quad pillar mount but I have switches stuff mounted where that has the 4th gauge placed.
