My LPG gauge shows correctly full (when full). At about half tank it begins to indicate less than true contents (have verified by checking the gauge ON the tank). It's a dedicated gas only system as produced by Mitsubishi.

Just below half tank (or thereabouts) it begins to show warning lights and the beeper warning also begins (annoying when its 100km to the next servo!). When down at almost empty on the dash gauge, it has 25+ liters left (checked when filling up).

Anyone else had this issue, or does anyone have any ideas? (apart from taking it to our local Mitsu dealer!) :kb:

Hmmm seems I'm in the wrong spot for 2004 Magnas .. but the questions the same :)

I wouldn't take this to to Mitsu dealer, unless under warranty, as they will farm out the work to a gas specialist, and add on a surcharge.

But I have a couple of questions for you, do you have two gauges, or just the regular petrol gauge indicating the level of gas in the tank?
And has it always been like this?

Those tank little gauges can be tricky, they look to be working as the indication on the gauge seems correct, but behind that is a resistor of sorts that can play up, getting dirty, or corroded etc and sending the wrong signal to your dash fuel gauge.

If this does not normally behave this way, I would go to a gas specialist, and that would be the first thing to check, takes 10 mins to remove, test and replace.

I have a single gauge on the dash, and a contents gauge fitted to the tank itself. It has not always had the fault, and it began a couple of months ago. I believe the tank gauge to be accurate after checking it prior to filling the tank at the service station. There's two wires exit from the tank gauge (with a connector) which are obviously the senders for the signal for the dash gauge.

So the gauge on the tank is removable without voiding the tank of gas? I had visions of them having to purge the tank prior to taking a look at it.

All I need now is a competent gas specialist.

I have had my 'ontank' Gauge removed with out losing gas, but some tanks may differ.
Different in cabin gauges my require different Ohm sigals sent from on tank gauges, if you head to BRC on the net the have a list of Installers in your state.

Thanks for that, I'll go peruse the net and see if I can find BRC.
