Fuel gauge wandering

Fuel gauge wandering

Postby MrBob [OP] » March 22nd 2014, 1:11am

My fuel gauge seems to have developed a mind of it's own. I'll start the engine and the gauge will read, say, 1/8th tank. I'll run some errands and when I start it again it will read, maybe, 1/2 tank.
The fuel pump is 3 months old and I installed the full kit with new arm and float.
Is this a voltage regulator for the gauge? Where is that thing located on a 2002?

I have the same problem with mine, sort of. Low Fuel Light will come on when gauge is low. I'll make some wild turns and a few stops and then it will show 1/4 tank. Maybe Image the sending unit??? Now I never let it get bellow 1/2 so I don't have to deal with it. I'm sure eventually it'll take a dump. Hopefully someone can chime in with a solution.

Mine does the same thing with a new fuel pump in it, the other day it pegged the needle for some reason, and stayed there after filling the tank. I call hijinks on the fuel pump wiring somewhere, not the sending unit or the gauge.
A temporary fix usually becomes a permanent solution, therefore it does not exist.

I have read many times that the fuel gage needle is wandering right after the change of the fuel pump, my Astro is doing the same. the previous owner had the pump change. not sure when ( over two years ago ) the bad thing with my van is that the fuel pump has flat out stop working twice now in less than a week, :shrug:

Since the pump was under warranty I replaced it and the fuel gauge problem went away. And, since I cut an access hole to the pump I was able to switch it out in less than a half hour.
