Air in the lines
So Im having an issue where I'm building up air in the lines or tank. If I manually operate the system and push the air out it works for a few days with full bars but then eventually drops bars, and then no bars. I have to repeat the process every other day. My tank is not vented so I'm not sure where the air is entering.

Re: Air in the lines
Is the air in the 6mm or the 4mm line?

Re: Air in the lines
I'm not sure, but I believe it's the 6 mm line since its affecting the flow sensor readings. My pump is also mounted upside down, would this affect it?

Re: Air in the lines
The only place where air can be sucked in has to be the inlet side of the tank. If you do not have a vent hole in the tank, the water/methanol cannot come out of the tank as the vacuum builds up internally.
Put a small pin hole about 1mm on the cap and tell me if it solves the problem. |
Re: Air in the lines
I Put a hole in the cap, there also is a rubber seal on the cap that I didn't drill through, but it's still the same.

Re: Air in the lines
It sounds like you have a leak pre-pump. Can you post a picture of the tank/pump setup?
The suction of the pump is strong enough to pull the air in. Re check the lines/filters from the tank to the pump. |

Re: Air in the lines
Does it make a difference if the tank is full or half empty? You could have a sloshing problem. Air doesn't always pass through the pump, but will sit in the head and cause issue for a while.
Is the fitting on the tank leaking air in under suction? |
Re: Air in the lines
I haven't noticed if the tank level makes a difference I will check that tonight, I will also cut and try to re seal the fittings on the pump. If you noticed, the pump is also mounted upside down on the tank, I'm not sure if that would cause an issue or not.

Re: Air in the lines
Do you have a filter between the tank and the pump?
