Default Pump location, priming, etc - using washer tank

I have a CM system that I am installing.

I want to use the stock washer fluid tank.

The opposite fender (under the stock airbox) has a lot of space and is perfect for the pump. BUT... it is not lower than the tank on the other side. That means if the tank got low enough, there would be air in the lines which I am sure is bad.

Is there any thing I can do, or is it an ABSOLUTE must to have the pump lower than the water level? Any tricks to this? I tried searching around but I am not quite sure what to search for. Is this what they mean by priming the pump? Keeping liquid against the inlet at all times?

Thanks in advance!

Jon

I havea a coolinmist system as well and I used the stock washer tank to hold my alcohol. I put the pump in the driver's fender right behind the battery. Fit perfectly and havne not had any problems in 5 months, 2 trips to the track and 3 dyno sessions.

where is the pump inlet in relation to the tank level?

i.e. - is the inlet lower than the tank, near the bottom, near the middle?

I just would get worried that if my tank gets lower than the inlet of the pump, that it will not prime and air in my line would also suck....

Thanks!

going to read that thread now.

EDIT - it seems the WRX washer tank sits kinda high. The legacy tank is way low down in the fender... with a feed tube up to the engine bay. I would guess your pump is lower than the tank.

with my tank being so low its almost impossible to get a pump LOWER

just mounted the pump.

I put it in the pass side fender in front of the wheel, behind the horns.

I made a platform as low as I could, and I actually think the pump is lower than the washer tank on the other side. Hopefully there will not be an issue with the 3 feet of hose between the tank and the pump. Since the tank is higher... there should always be liquid in the line, and not air.

So what is the deal with priming the lines? like before going WOT.... get above my setpoint (9psi) just to turn on the pump and get some liquid in teh lines between the pump and nozzle? I did not think I had to worry about doing something like this.

Thanks.

If you are using the boost pressure switch just ground the negative wire that goes to the pressure switch. I did this by unplugging it and touching the wire to a strut tower bolt. The pump should turn on and liquid should spray. If you want to leave your IC disconnected you can watch the water spray out of the nozzle to make sure.

This shows where the pump is mounted. It is below or at the very bottom of the tank.
