Prado 120 dual fuel transfer failure

Toyota Prado 120 series often suffer from a failure to transfer fuel from the rear 90 litre tank into the main 90 litre tank, causing them to run out of fuel although not empty. Drivers also have trouble re-filling the tanks when this happens. This has caused much frustration. The solution is cheap and simple. This also applies to later models with dual fuel tanks

This helps a lot. I pulled mine out and found the pump had been replaced in the past but not plugged in! I also found the transfer filter blocked. Plugged in and tested the pump and renewed the fuel filter. I didn’t check the Venturi though and put it all back together. Seemed to work for a while but has stopped again. I’m going to have to pull it out again!

Oh Man, I wish I had seen this video along time ago, im having this problem right now on my 2008 Prado. Thanks alot

Its called a jet pump. It uses a hi pressure, low volume flow through a venturi to create a high volume, low pressure pump. Simple but effective, at least until you get junk in the venturi.

Beautifully explained boys. Thank you very much.

I have a switch over problem on my 2004 Lexus LX470 is it a similar problem and fix?

[Westerworld]

My Prado has an issue, and I am wondering if this is the reason. 
When I start my Prado (KDJ120 - 03/2006), the engine turns over and start, but immediately shuts off again. Batteries, keys & immobilizer are checked and works just fine.

I pulled off the fuel supply line on the fuel filter in the engine compartment - turned over the engine - and none fuel came out. 

I still have to check the fuel supply pump. If its working - could this be the reason for the issue I am experiencing?

I have a Prado 120 and the car stopped today seemingly due to fuel starvation. I had about 100 liters fuel, so 90 liter in one tank, about 10 liters in the rear tank. After waiting for the fuel pump and car to cool down, I was able to start again. Do you think the culprit is probably the venturi? I suspected that the fuel pump itself is the issue.

how the heck did you remove the "large fuel line" at 0:36?

Please help, i literally spent 20 minutes attempting to take it off and run out of daylight :(

Hi  Shem Tewkesbury, my prado150 1kd 2012 flashes the fuel light on/off despite fuel gauge at middle. When I fill up, the flashing fuel light stops flashing...Do u think venturi or secondary fuel filter?

[iancook]

I have a 2012 Prado 150 series with a sub-fuel tank and have just had the fuel transfer pump replaced. However the fuel light is now flashing ( the fuel light NOT the one with the 2 lines of dots underneath) when I get down to about 700 km to go - fuel gauge approx at middle.. I presume this is when the tank changeover occurs? I topped up the fuel and the light went off, but it came on again when the fuel went down to approx the same level as before. I thought the ECU may need resetting and did this but no change. I have also checked the relevant fuses.
Any solutions / ideas????

Mine is a 2003 first month of the 120 series I don’t have the internal pump as shown in the video think mine uses main pump I had no blockage in Venturi still NFG note my model does not have a transfer filter

[warrenblackburn]

hi, does the fuel pump stop working when the jet pump blocks?

[MADBONE]

would it be ... a good idea or a bad idea to widen that hole with a 4mm drill bit ... to stop more particles clogging?
obviously we want to stop the particles but it needs to be stopped at the Fuel Filter thats its job haha

Wear is the sender, mine is up and down all the Time even when I have put fuel in it .
