VY V6 Fuel Guage moving very slowly.

[Pie-VK]

I'll set the scene.

I was running a bit low on fuel this morning, so before work I chucked $50 of 98PULP in and headed off, but my fuel gauge didn't move like normal. the computer said I still only had 110k left in the tank. I know fuel entered the tank because I heard the nozzle squirting ouyt the fuel and I could hear fuel entering the tank.

over the course of the day my fuel gauge has risen, but only very slightly, it now says I have 180k left in the tank and the gauge has moved up about a quarter of a tank.

My girlfriend said that this happened before when she borrowed my ute, but by the time I got the ute back, everything was fine again.

I Have an old commodore manual that says that I have to remove the tank to check the sender, but it doesn't cover the utes, and I know the tank is directly under the removable tray panel.

Is there any easy fix for this? or do I still have to drop the tank?

Fuel sender Resistance Problem. Might be a dirty contact. Sh** fuel over time will speed this up. Pull your sender out and see what the connections are like you might have to clean/replace it. My VY Clubby did this once. Problem was a bad battery, had all sorts of electrical issues before i replaced the battery, including the sender issue.

Have a look in the hand book with ya car and it,ll tell ya,small amounts of fuel can take up to 10 mins to register,so $50 at say 1.45cpl would mean around 35 litres,which equates to say half a tank. Mate next time fill her up and see if the gauge rockets straight up to full.I wouldnt go spending replacing anything just yet

I experienced this issue yesterday.

Fill up the tank. Only registers half a tank.

Dunno what to do.

take the battery - off and on and rest ecu.

I had a similar experience except it was only when the tank was completely full ie. fill up tank and a minute or so later I would get a low fuel warning and the gague would drop to empty. Go around a corner / bump etc and it would register full and the do it again a few seconds later. Then it would start reading correctly after 30km or so once the fuel level dropped a bit.

I put ~500ml of metho in the tank (no E10 in Perth at that time) and filled up in the hope it was varnish / corrosion at the very top of the fuel sender potentiometer and it would clean it up. No more problems since and that was about 1 year ago, so I would give a tank of E10 a go.

Of course if the problem is across a lot more of the senders range it might not completely fix the issue.
