GU fuel pump from sub to main tank

Would an electric feul pump suffice,,, Autobahn, Repco, Burson's, or one of those aftermarket places should l have them .

Word of warning ,,, get a good one, I think about $100 should do, but I could be out of date with those prices.

I would be concerned about why this is happening.

I had the fuel pump in my Patrol replaced a few years back.

Are you sure it's the pump , not the control unit ? Tried disconnectingbattery for 30 minutes to reset it ?

I had mine seize up after it shorted as i think some dust/mud got in past the small breather on the unit.

After taking it out and trying to pull it apart, i just gave it a couple of hits and this loosened the unit it up and its been working since (this happened 12 months ago).

Must be something that is causing it to fail that quickly.

Hi D,

No they cannot be repaired. I managed to get one apart and found that it is a pretty complex pump with its own circuit board that drives a solenoid and long 'pill' with a one way valve in it (not a rotary pump). The whole lot is sealed in the metal case with expanding foam and some bloody strong glue and a couple of bolts.

I am on my 3rd one now and would love to know why they die. First one used to got real hot before it died. Second one was a secondhand one and it died when I had 450Amps run through the chassis rail from the winch trying to find an earth. I just had it replaced under insurance with a new one a couple of months ago.

cant see why an after market one will not work. all pumps are pushers or pullers, fast or slow transfer. with a relay off the original wires and a pusher like the one repco sell for carby cars, this should work. the pump will stop when it builds up pressure.

It's strange to me....I owned my first GU from new in 2000 until earlier this year. Did about 212,000klm and never had any problems with transfer pump. Current Chev/Nissan Patrol is also a 2000 model and same thing (although I don't know for sure that previous owner/s didn't have a problem, there is no evidence from receipts I inherited etc).

One thing I always make sure with my Patrols is that there is ALWAYS a decent amount of fuel in the sub-tank. I have heard of some blokes who leave the sub tank empty and only fill it when they plan a longish trip. Bad idea as far as I'm concerned. I also make sure I use the transfer pump every time I am close to emptying the main tank....IE: I fill both my tanks and I always use both tanks (my sub tank is an aftermarket 80 litre jobbie too).

Now to the idea of a replacement pump..... I would recommend a FACET pump (Google is your friend). I cannot say whether it can be wired directly into the existing switch, but can't see why not; they both have a simple pos and neg wire. However, if for some reason it cannot be wired through the original switch's wiring, I would have no hesitation in wiring it up to another, separate switch......you would just have to remember to turn the pump off after the sub-tank gauge reached empty.

Facet pumps are about $100-.

An after market pump can not be wired in and the system work as standard because the subtank light will say on as the system will think there is an errror with it because it will know the factory pump is missing.

Having said that, as suggested previously it might be worth fitting an aftermarket facet pump with its own switch.
You will then need to turn it of when the main is full or the sub is empty and ignore the sub light (take out bulb) this will save you a few bucks. Also need to fit filter before pump.

I have heard the following coments from patrol owners, but never checked if they are correct:
Does the fuel system have a filter in the line before the pump?
Does the vehicle run the sub pump for a few second every time you start the vehicle (is your sub empty)

Had a similar problem a few years ago with a F150. The pump in the auxiliary tank cacked it. So I installed a reciprocating pump to pump fuel from the auxiliary tank to the main tank and a switch on the dash. Worked great and cost well under a $100.00

I also recommend a Facet pump... there is no way I'd be refitting a $700 pump. I'd do what ever mods were required to get around that.
I use a Facet both for pumping from my aux tank and also feeding from my main tank, though a pre filter (Frantz) then factory filter to the injection pump.
Meanwhile my GQ has never had anything go wrong, and the only "parts" I've had to replace apart from filters/oil/grease/brake pads and the like are those silly plastic rear sliding window catches.

It is easily the most reliable vehicle I have ever owned, and by a huge margain! Why are the later ones less reliable? (Because they make no money on parts from people like me!)
