Re: How to Properly Ground Fuel Tank
Ultimitley, the negative battery cable. It may be grounded to a big component like the engine if you have an I/O. A bad ground is your worse enemy in electrial systems. They cause electrial components to act badly. As far as wiring a ground wire, mine had a tab welded onto the takk, and a hold was drilled thru the tab, I just put a thick gauge wire with a soldered terminal and heatshrink tubing and secured it with a brass nut and bolt, That ground wire terminated at a spot on my engine ( I/O ). MY fuel gauge sending unit had a seperate ground wire shared by all the gauges.
You want to have a ground wire from both
the filler neck and the tank for safety. Electricity follows the path of least resistance, so if you have a spark from static, it has a place to go. It also helps with corrosion on metal parts. The current generated by corrosiob is discharged through the zinc annode on your boat. Well I think I'm accurate, but if not I know someone will let me know :o
