If you want a really good deal on some better gauges than Glow Shifts (I've read a lot of negatives about them) contact Ken for a complete set of Isspros. NCHornet referred me to Ken because he has the best deal I've found. Ordered my complete tripple pod kit for less than $300 shipped to my door. You can email him and tell him NCHornet and Shane sent you.
For the fuel gauge pressure, you would want the one that goes up to 100 psi. Ken also offers the 4 gauge pod for the same price as the 3 if you plan on running a fuel pressure gauge as well.
