yamaha fuel management question

[willxfs]

Ok so I bought a used kit and it is definitely the guage for dual enging applications (as well as wiring harness). I will be using it on a single engine boat. My question is can this guage hook up to a gps to display miles per gallon. Thanks -will

Thanks for the link. Good info. I checked my guage and it only has four pins/switches. Anybody have a diagram for that set up.
