G'day everyone

We were given a 1995 Patrol to drive up to Karumba over the weekend from Mt Isa.

The advise given to me when we left was the main tank was useable even though the sub tank light stayed on and the sub tank was full I wouldn't be able to use it as the switch wouldn't work.

I hit the switch while driving to se if I could get it to work even if the switch still stayed on the sub tank. No such luck.

Is there any trick to it or does the owner have to get a new switch.

Regards BooBoo

Hi BooBoo,
common problem with patrol.Remedy is usually to take the battery leads off for 15 or 20 minutes and let the ecu reset.The sub pump is ground to the chassis and there is no really good grounding unless you fit an extra grounding strap to the bodyand chassis.

Well Dave I tried that.

The sub light went out when I started the motor, but now when I press the switch the sub light does not come on. I hope I still have the main tank connected. LOL

The owner tells me it is going in for a service soon so Nissan can have a go at it.

It was worth a try though, thanks dave.

The main tank has to be under 3/4 full.
Cheers Dave...

Hi BooBoo,
thank's to Dave(NSW)'I should have mentioned that.If the green light is now off ,the sub should pump when required after you have used a 1/4 tank from the main ,no point if your tank's full.

I'm puzzled.... I didn't realise the GQ (which was the model in 1995) came with a factory sub tank option??
