Fuel Management ??? (Jim- BOE - you around ?)

[oldbluesplayer]

Guys - thinking about my 20' Seafari, results from last year, and my intentions to get semi-serious about chasing Charlie this coming year, I'm thinking I need to add fuel management to my boat -

early in the season, I tried to drain off my tank by running, (getting ready for the switch to E-10) got to an apparent 1/4 tank -Below- "E" and was still running - so I know, that I don't know, what my fuel guage is telling me -

So - Navman, Lowrance ??? simple is better - but I want a fuel flow guage system - 1 tank/1 motor - something where I tell it what the fuel tank size is, it reads gal/hr, and tells me fuel burned / fuel remaining - don't need anymore - just where I'm running at, gal/hr, for fuel efficiency, and what I've got left -

Thoughts / advice - suggestions ?? Reliability and accuracy are primary concerns.

thanks

Bill
