Atessa bleeding with vacuum pump

I am looking to replace the Atessa system fluid and wondering if I can use a vacuum bleeding pump setup to flush system from front to back or vice versa? Then do standard air pressure bleed if required? 

And yes I have searched and found the standard ways to do it with powering pump etc, but looking for one man operation options. 

Other thought is whether system cycles every start up I could vacuum out reservoir and wipe etc, then put fresh fluid in every couple of weeks until it's reasonably diluted to an acceptable OCD level ha ha ha ha ha ha.? 

Hit me up with options peoples.. Then once this has been achieved I'll do the diffs  and transfer cases

no need mate, as long as the pump is running it will bleed the system. It's not like brake or clutch where the pressure comes from a pedal being pressed.

 

If you want to run it long enough to flush all the fluid through just keep an eye on the reservoir and refill it as you go

Okey dokey, I just thought it has several bleeding points so it might need to be pressure bled so to speak, and therefore deduced the vacuum method might have bypassed the airlock bit of the process

yeah there are 2 bleed points but they are both downstream of the pump obviously. just crack the one above the rear driveshaft first and then do the one at the rear of the transfer case once the first is done.

I don't think I've heard of anyone having trouble with an attessa bleed unless they either had a problem with the system, or they didn't notice the bleeder above the rear driveshaft

      If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.

      If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.

      MAJOR FUEL ISSUES 25det neo r32

      Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
