Bleeding a IHDFTE Toyo engine?

At the fuel filter there is a hand pump on top, remove the line to the fuel pump and hand prime the fuel through the filter, once the fuel comes through (obvious) reconect the line to the pump a further 3 or 4 times and then start the car.

I have run out of fuel a few times in my Toyota diesel and I just switch tanks, pump the filter until it is hard, start the car and head off. Nothing to it.

Please DO NOT run your diesel tank dry!
The modern rotary injector pump and the injectors are lubricated by the diesel oil, and running it dry will cause damage, especially on the common rail diesels where the tolerances are much finer.
The older diesels are more tolerant, however it is still not good for them

The Toyotas and a lot of the others can be primed with the hand primer on the fuel filter with out disconnecting the fuel line.

Yeh its not a good idea to run any fuel injected vehicle dry, the fuel is used as a coolant and lubricant for the pump and injectors.

almsot all modern vehicles have a circular fuel system where the fuel pressure is regulated by blowing off excess fuel and returned to the fuel tank..this is constantly happening...this circulating fuel also acts as a coolant.

My diesel hilux has a 90 liter tank and it reads empty and the red light is on with abot 20 liters still in the tank...I have never pumped more than 75 liters into it..

Fuel is constsntly sloshing arround and being circulated by the fuel return, when you get very low in a fuel tank there is less fuel between the lumpy bits and there is more liklyhood that they will be picked up.

Also may fuel tanks contan a swirl pot, where the warm returning fuel is mixed with incomming fuel arround the pick up.....this tends to keep rubish away from the pick up.....when the tank is getting very low..again there is less fuel between the lumps and the swirl is not as effective.

ALSO, in diesel pumps because the fuel in the lubricant, having air sucked into the diesel pump and thru the injectors is not a good thing at all.

BY far not a god idea to run a diesel dry

Yes while you can pump the primer on the filter and the engine may start with a spltter..its not the recomended thing.

you bleed the injector line by cracking the nipple nuts on the injectors like you do on almost every conventional diesel motor ever made.

Serioulsy do yaself and him a big favor....buy him a service manual.

the Haynes 92737 covers all models of that series, the Max Ellery EP.T034 while it is a prado manual covers that engine and most of the hilux mechanicals of that era.

Best to buy both, one covers the gaps of the other.....you will not buy a genuine manual new.

cheers

Priming diesels is getting easier. For the last 23 years on Landcruisers its just been a matter of lifting the bonnet and pushing the primer button until hard. The air gets pushed back via the return line into the fuel tank it came from. If the button doesn't want to go hard then sometime removing the cap off the fuel tank helps by releasing the suction. Sometimes, with age, the primer pump doesn't work too well - from memory it costs about $200 for a new one from toyota.

I never take off the outlet pipe from the filter - its a surefire way to introduce a bit of dirt into the injector pump. I prefer to change filters with the hoses attached. You can however take off the fuel return hose off the injector pump and wait for fuel to flow from it.

My wife's VW Tiguan is simpler again. It has an electric primer pump in the tank - just turn on the ignition about 5 times and the fuel line is primed. It also has a fuel filter that is twice as big as the Toyotas!

Well what a lot of mixed replys this has been,......Iwould luv to have all you guys around a diesel thats run out of fuel...What a argument that would be..lol.lol.

In my experience with landrover, isuzu, and a host of older style diesels, you always bled the filter, then the pump, and with some of them there was no way in hell they would go until you cracked no 1 injector,that usually depended on just how dry it was run. Hence my question regarding the hdfte toyo motor, with no bleed screw at the filter head andthe pump all covered up, iwas thinking these things are a piece of cake to prime or a absolute pitta, seems you can just push all air thru the system to the return tank line very quickley, not the case with some older diesels,...what about filling the filter before fitting, save the hand primer a little bit of wear?, or i suppose your using unfiltered fuel then, or are you? if its poured straight into the filter?

Thanks for the info so far anyway, never to old to learn things

Cheers Axle.

Axle,
with all this bleeding going on I hope someone called a doctor.

I've run mine out a few times. Most common way is to switch to the sub then forget to put it to main after refueling(no low fuel light for sub) then a couple of hundred ks after refueling the old girl dies (no brrp brrp just stops dead)
