Greg,



Are you using EI or VMS probes or building your own?

 Scott I'm just finishing the PCB layout using Jim Wier's design.  At 

 this stage I'm going to use a panel meter for the fuel gauge.  Later I 

 might make another processor board for corrections since its not a 

 linear output.  It will probably handle different fuels etc.

Neither, Vans sells a kit that fits into their fuel tanks.  If I new they 

were this much trouble before hand I would have gone the old fashion route.
