The oil and water gauges are electrical and come with the associated sending units. These gauges are isspro's classic series.
As of the beginning of this year, isspro didn't offer an ev2 gauge in a 10-72 ohm fuel range but said they could custom make one. The speedometer was the only gauge that I was missing to make a complete kit, but I'm not sure if it is available yet. I have some ev2's in my powerstroke and they are nice gauges. Cost will probably be a couple hundred more minimum as they are much more expensive.
There is no price difference if you swapped the vacuum gauge for a trans temp gauge and sender.
