Pump installation concerns

[Drachonyx]

Question for CoolingMist that might interest some people (I hope):

I'm currently installing my W/I setup and I have some concerns with the placement of my pump:

1) I decided to install the pump in the driver's side fenderwell. However, since I have an AEM CAI, I'm lacking some space to install the pump so I'll put right between the headlight and the foglight. The pump would be mounted horizontally, input from the tank (it's located behind the driver's headlight, fits like the space was left by Dodge to put a W/I tank there ) on the bottom and output of the pump at the top. Is it acceptable? Would the pump have to work too much more to build pressure?

2) Another question: I currently have the 1/4 to 3/8 NPT elbow / checkvalve pair at the output of the pump. However, due to the position of the pump, this elbow is too high. Would it be acceptable to use your "(3/8 NPT Male to 90 degree 3/16 Barb)" fitting at the output side of the pump with the 1/4 hose you sell? The hose seems to be secured tight enough, but I prefer asking than be sorry.

Thanks!

Hi, you can use the barb fitting no problem. I would test the pump in that position. I hate to give a difinitive "yes" or "no". Test it in that position before you make it perminent. Please reply back to the thread after. Typically the pump should be underneath the tank. THe pump can be mounted usually in any position (upside down, etc).

My tank is the 2 quart one, is tapped at the bottom and is over the pump by about 1.5". There is 12" of hose between the output of the tank and the input of the pump.

I just tested my pump and it seems to prime really quick. When I flip the switch, the response is instant. The pump is pulsating and the spray from the injector don't seem that strong thought. My VariCool controller isn't plugged to the pump; I get the power source straight from my car's battery (but it has been sitting in the garage for 2-3 months, so it's getting weak, maybe that's the reason for the low pressure).

You should NOT use your cars battery for power source. Use switched ignition. If something goes wrong (controller short, or accidental grouding of pump) it will cause your injection to fill your engine when the car is off. That could hydrolock your engine. We put 12V switched ignition for a reason, please change it asap or you may regret it someday.

If the pump is pulsating that means you are hitting full pressure. It shuts off at 140-150 PSI. You will have somewhere around 130 PSI after the checkvalve.

Oops, sorry that I didn't mention it in my previous message: I used a direct connection to the battery for the sake of the test only. My WI system's wiring is not complete so the pump ain't connected yet.

And don't worry, I'm playing safe: my W/I system gets power only by switched ignition. I got a relay between the 12V source (from the PDC) and the controller that is activated by ignition, and can be shut off by a switch.

I'll take a look at the Vari-Cool controller's documentation to eliminate pump pulsation.

Thanks for the help!
