Earthing tank components.

[gtflash]

Hi. Original Scorpion Inboard grp tank which now has two new stainless inspection plates through bolted to tank. One has fuel filler and breather and the other has nmea fuel level and pickups.

Should I tie these to -ve battery? I will fill from land stations and water when she’s living afloat again soon.

Because the tank is GRP there is no need to ground the fittings. are you worried about corrosion or sparks from static .

The existing setup had stainless pickups and breather and fill so I’m not concerned but I noticed it is discussed a lot. Especially in US forums.
