Fuel pump ground location?

‘89 F-350….anyone know off the top of their head where the fuel pump ground (coming off of the module) terminates?

The fuel pump circuit ground is near the windshield washer bottle, either on the inner fender or the radiator support.

Copy that! Bought a Dakota digital instrument panel, and they’re specific about inputing the fuel pump ground to their hardware…thanks! 👍🏻

That ground location is common to the headlight circuit also. I don't know if that will matter to your aftermarket gauges.

It may not matter at all..it seems like that portion of the instructions is more generalized, since they say it’s recommended for accuracy, and talks about a grounding wire off of the pump sender plate…those of us that know, know there’s no fuel sender attachment bolts 🤷🏻‍♂️

May end up rolling the dice, and snagging one of the grounds going to the cluster. Guess if there’s issues, I can always do it their way.

There's generally a main harness ground in the driver's kick panel.

What I use for anything in the cab or dash.
