Does the tank need to be above the nozzle? I searched and have found bits and pieces regarding this, but nothing clear. It seems there may be an issue if you mount the resevoir lower than your nozzle?

I am hoping to order an AI kit soon, I need this clarified.

 

It shouldn't matter. I'm assuming that you're pressuring the reservoir with boost pressure.

 

The tank should be above the pump when using a pump. If using a pump then the tank does not have any relationship to the nozzle unless not using a one way pressure valve.
If no valve is used then the tank has to be lower than the nozzle to prevent siphoning.

If using a boosted tank like Rice Racings setup, then it would be better if the tank is higher.
Then you have to address the siphoning issue. But using a liquid flow control solenoid solves that problem.

It all is simple basic science.

 

Which setup did you go with, chuck? I'm on the fence about it.

 

By that I mean mechanical or electric pump.

 

I went with an electrical system due to not having enough room for the tank up front on my car. I did not want to deactivate my windshield washer.
