Gq gauges

[Parksy]

Hi all

I was wondering what people have thought about the gauges in the gq dash,
Mainly the fuel and oil pressure ones when it came to accuracy. I find myself filling up with petrol early because I'm not sure how low the gauge actually goes. Can an aftermarket unit be easily fitted using the factory sender unit?
Does the oil pressure gauge actually work? When I switch the ignition to on, but not with engine running, the pressure gauge does go up, and when the engine is turned on, it rises again and does change slightly when the throttle is blipped, but I'm still skeptical about its accuracy. When warmed up it says pressure is about 1-2 bar. Does this seem right? Curious to know what everyone's readings are on this gauge.

Thanks all

Andy

As with any electrical gauge, the reading depends on its voltage supply. On longer trips, the battery will be fully charged, so even with the regulator doing its job properly, I have found the gauges read ever so slightly higher. My petrol gauge is very inaccurate between the quarter marks. 70 to 80 kilometres from full to 3/4. Up to 120ks then; hang at half full for ages. After that it falls away to 100km to 1/4 and I have never had the guts to see how far it will go to empty. My oil pressure gauge alters with engine temp as well. So as the pirates say; "Its more like guidelines than rules."

I just turned the ignition to on, and my oil gauge stayed at zero until the engine was started.

Thanks mudnut, I don't feel so bad about the fuel gauge now, but I think I'll go aftermarket with the oil pressure.
Cheers!

Sorry, Parksy, that's all the info I've got. Forum members with more experience may be able to advise you if it is a good idea to upgrade the sensors or not, and which units are the best to get.

Lol yeah my fuel gauge is slowly getting worse. When I fill up it only goes to just above 3/4. It stays there till I actually have 3/4 fuel left then it reads fairly accurately down to half. Then below half it drops away real quickly (quicker than I'm using fuel). Best way to check is to put a jerry can of fuel in the back and drive till you run out (which is about a quarter below the empty line lol

When I pulled the sender unit out of my Maverick I found that float arm was short and showing empty 60mm above the base of the tank, so have lengthened it to show empty 15mm from the tank base. In my Hilux it would go to within 8mm when showing empty.

Thanks pezzer, might have to give it a check. How did you check it btw? Was the sender still in place when you checked?

[Pezzer]

It was when I dropped the tank and pulled the sender unit, I noticed that the float was still above the pickup by quite a bit when it was hanging so I measured lengths as if installed and checked the tank depth, would never of known otherwise.

I agree Tas,

But also set your trip meter, and drive it as far as you are game or until it does run out. My fuel gauge seems to work ok but I still set the trip meter everytime I fill up.

It's a little peace of mind.
