Air Bubble In Atessa Resevior

[Simonster]

Hi,

I have noticed recently when turning on the ignition, an electric pump (not the fuel pump) underneath the back of the car ran for a second or so. The time it ran for slowly increased so i checked out the atessa reservoir. It seems to have a section towards the bottom where there appears to be an air gap.

I gather this is what it is, and the filter may have something to do with that.

When you look at the reservoir the oil level is fine but there seems to be an air-gap towards the bottom of the tank.

Is there anyway to remove the top of the reservoir and take out the filter??

Any guidance is appreciated.

Anyone have any thoughts or info on this?

I though they were all like that (mine is)

Pretty much mine has a 4mm air bubble around, think that's normal

Ah ok. I suspected that it was a problem cause when i turn the cars ignition on, I can hear a motor running for a short period of time, i gather its getting the atessa up to pressure. That motor is running for longer now, around 4 seconds whereas a number of months ago, it made no noise at all.

That's why i thought the air bubble was not normal.

So what would cause this motor to run- low fluid. I've checked the leves and they are fine?

Thanks

attesa pump always should prime for a few seconds when you turn ignition on. many people mistake it for fuel pump priming but in a standard-ish GTR (with say bolt in nismo pump or standard pump) the attesa pump primes much louder than the fuel pump. approx 4 seconds sound normal to me.
