? about bonding fuel tanks

[PipeDreamsMarine]

The fuel fill neck should be grounded separately from the tank ground. Both should be well grounded to the battery.

I also have an 8"x3" bronze grounding plate on my hull which provides over 12 square feet of grounding surface area in contact with the seawater. Since my zincs, motor, and electronics are also grounded to this plate, it really helps eliminate any electrolysis from happening apart from the zincs.

Please re-think this statment.. 8" x 3" is not 12 sqft of area.. Filler neck should not be grounded to the battery it should be tied into the bonding system, tank should be grounded.

No 12volt grounds should be put to any bonding system. Only frame grounds that are not used as 12 volt grounds should be added to your bonding system( ie antenna gounds or IG grounds)
