fuel flow drawing wanted, can't see how return gets in tank?

[Bart F-350]

sometimes yes and sometimes not, I've broken open drivers side 2nd and pass side 3and 4th the others I daren't, when I start turning the nut, the line turns with it.
and when the engine runs, it doesn't stay running, therefore yes and no.

That's more likely than not because of the air in the lines. When it does fire give it a little throttle to see if you can keep it running.

I'd say crack those other injectors open but I don't want you breaking the lines or anything!

It's a good sign of progress though!

when I start turning the nut, the line turns with it.

My guess is that the injector is also turning. Try putting a 1" open end wrench on the injector to hold it still. Hopefully that will work.

If it's really empty cracking the injectors will speed up the process. But unlike other diesels with no return lines, these will purge themselves of air eventually.

You can put a primer pump on the frame tied into the feed line to aid in getting fuel back to the filter, I did that on a topkick with a cat to make filter change easy.

That is not the same quality one I found for it, it looked more like this being all metal but cant find one like it.

I'm not aware of diesel engines without retour??? do they exist?

Until now, I used a electric pump for that, though I had to disconnect every time after that. and that of course reintroduces air in the circuit..... AAAHHh ja :-0

Worked on a skid steer the other day that did not have the return system on the injectors. Many other pieces of equipment do not have return lines. On those machines, you run it out of fuel and YOU HAVE TO crack the injectors or it will never run.

I still can't get the bloody mouse to squeek!
I can't get my hands on such a pump and get it to work here. and after thinking about the circuit the return diesel has to go, I have the idea/feeling, that the return diesel flows without any pressure, via the "T" piece near the firewall right back into the tank.
So unless I make a mistake in my way of thinking, does such a pump have effect?
And what if I employ a universal anti retour valve there where the brass ducks beak valve used to sit?

This is right. There's suppose to be no pressure or almost no pressure in the return system.

So unless I make a mistake in my way of thinking, does such a pump have effect?
And what if I employ a universal anti retour valve there where the brass ducks beak valve used to sit?

If I am reading this correctly, and I may not be, it seems like you are putting the pump in the return lines somewhere. If so, that pump is supposed to go in the supply side, between the fuel tank and the engine.

 

[Bart F-350]

I'm trying to write down what I think that I have done yet.
(sounds stupid, But I might have made a mistake somewhere, because the engine will not run, I've had it running, but after a few seconds it stopped again and cannot get it to run yet :-( ).

took off both tanks and cleaned them,
cleaned fuel pickup's and fuel lines,
changed filter head and filter,
filled tank, with electric pump sucked fuel to lift pump, then connected lift pump to fuelline, sucked fuel through hardline where it goes into new filter,
then sucked fuel trough filter and pressed fuel into injection pump. ( somewhere here I blocked off the "anti retour valve or whatever its function is" off with a bolt and hoseclamp.)
Engine ran for few seconds and died. cracked injector nuts, engaged starter, fuel at all injectors, closed nuts, started, ran for few seconds, and couldn't get it to run since, emptied my batteries trying.

I'm losing motivation here, I can't see why she's not running?
I assume maybe some air in the retour circuit?

Watch the tailpipe while you are cranking. No stinky white smoke coming out of the tailpipe means no fuel is getting to the engine. Stinky white smoke means you are getting fuel but not burning it. Are you using the glowplugs? Yes, even in the hot summer you need to use the glowplugs to get it to fire.

 

[Bart F-350]

yes, I use the glowplugs, but I can't see the exhaust.
nobody around either.

 

[franklin2]

Don't worry, if you cranked it enough to run the batteries down, and you had fuel, there would be a cloud behind the truck that would be unmistakable.

 

[franklin2]

If you have a electric pump, leave it hooked inline and running, and start cranking. It should eventually start.
