OK, first part of the job is done -UK-spec rear washer bottle installed, pipe to engine bay ditto. Now I have to work out where to put the pump...
I\'ve seen one or two installs, including one that looked like it was in the boot (didn\'t strike me as a good idea, I\'d rather have the pump near the injector), but I\'m still unsure where to stick it. Where have you guys who have it installed already put it?
ive put mine under the front bumper although i have a veilside front so probably have more room that under the stock bumper
Hmm, that\'s a thought - did you have to remove the whole bumper to do that? I\'ve got a C-West so likewise, probably have more room than stock.
Does it get in the way of the radiator/intercooler ducting at all? And do you mean actually "inside" the bumper - can\'t see how you wouldn\'t screw through to the exterior though?
My pump is in the boot in the compartment on the left (where the tool kit is-obviously not anymore) !!
Havent seen any reasons why putting it there is bad, it\'s closer to the water tank than in the enginebay and obviously not affected by the heat generated there. The pump is perfectly fine to pump the water the length of the car to the twin injectors.
Just my opinion though, been using it for over a year with no issues. I followed Scott (sdminus) advice when fitting it so if it was good enough for him it was good enough for me.
yes removed the bumper and welded a couple of small plates onto the front of the chassis. at least there its out of the way of everything.

Hmm, that\'s interesting - I was going on what the Cooling Mist instructions said (and something I read on the Aquamist site too), but neither seem to be vehemently against it, they just say "put it in the engine bay". I suppose once the system\'s under pressure it doesn\'t really matter where the pump is, water will come out at the same rate.
I am tempted by that option, it makes life easier and everything fairly easy to get at. I presume you wired it up from the rear light or rear washer loom? Any tips on which wire is which if I do go down that route!? :3Confused
It depends on which WI system you use. The Aquamist HFS systems specify that the pump should be in the boot (or close to the tank, wherever that might be). The failsafes, HSV and flow sensor take care of the inherent disadvantages of such a long run between pump and nozzle.
I think, from memory, that the coolingmist setups need a shorter run between pump and nozzle but it\'s a long time since I looked at their sytems so don\'t quote me on that.

Hmm, I do have a checkvalve in my kit, which is meant to sit between pump and injector, so maybe that would prevent such problems?
I\'m not even sure what the problem might be - surely once water is in the whole system (i.e. it has been used the first time), as long as you don\'t run the tank dry, it will always be under pressure and fire properly?

Coolingmist is the same - pump needs to be close to the tank, as they aren\'t very good at \'drawing\' on the low pressure side - you can engine mount the pump if you use a low pressure pump to feed the main pump, but it will happily push 150 psi up a few metres of thin nylon hose. Probably better to rear mount it too, as the thing is huge
Yeah, it ain\'t small, that\'s one of the problems with mounting in the engine bay! :chat I suppose they\'re expecting you to put the water tank in there as well, hence the instructions.
Right, you\'ve pretty much made up my mind that having had the entire boot trim off to fit the tank, I\'m now going to remove it again to fit the pump in place of the passenger-side toolkit... :2Rolleyes ;)
Any tips on wiring please? If I remember, the workshop manual doesn\'t reveal the colour-coding for the wiring looms, so any knowledge about which is live/ignition/ground is most welcome!
Did you guys wire up to the rear looms or run the wires all the way down the car to the main dash loom? I guess it might be easier to do that as the rest of the electrics will be down the front (boost switch, operating LED etc.)
My battery\'s in the rear bins so I just ran a feed from there.
I ran the control wiring up to the front using the loom box that runs along the passenger side sill (inside the cabin). There\'s enough room in there for a water pipe and the wiring, but only just!
Hi,
For a different perspecive, mine is mounted in the space where the front light used to live.
I have the twin round head light conversion, so the pump fits nicely in the redundant space, which is next to the original washer bottle which now contains water and methanol 50/50 mix.
I use the rear washer bottle to supply water to the front and rear screens.
Thanks guys. Went for the boot/toolkit replacement option as it was the easiest/neatest and once in place seemed to work fine (i.e. water came out of the pipe at the other end when tested!) However, having gone to the hassle of locating a 1/8th NPT thread tap and several hours work (mostly my future father-in-law\'s, but hey...), it now seems to have zero effect on air temps!

I\'ve been told by Cooling Mist that the cause of my problem is the pump not being below the tank (i.e. gravity fed). I\'m getting an air lock at the input (pump) side of the checkvalve.
Does anyone else have a Cooling Mist setup with the pump above the tank? Gmogle, you say yours is where I\'ve put mine (replacing the toolkit), is it a Cooling Mist setup and if so, how come yours works and mine doesn\'t!?
My setup is:
Tank > Pump > Checkvalve > Clog detector > Injector
Yeah mate, mines a coolingmist one (dual stage wi kit), I also have a UK spec water tank and its plumbed in there and not having any issues. Silly question but is the water line reaching to the bottom of the tank ?
Any airholes in any of the piping ?
Guess the pump is the same ?
Well, I tapped into the water tank using the supplied push-fit connector, which seems to take water fine, although there is a very slight leak - don\'t see why this would cause a problem though?
No airholes I\'m aware of, there\'s no water anywhere to suggest a leak. Pump looks identical to all the other ones I\'ve seen in pics of installs.
Someone has suggested putting a one-way valve between tank and pump, might give that a try, but I don\'t really understand what\'s going on as surely once water is in the full length of the system, as long as you don\'t run dry, it will always get water?
This is just aimchair speculation, but if the pump is above the tank, then when it stops pumping, surely the water would flow back from the pump to the tank? leaving air at the pump...?
I\'ll tell you when I\'ve fitted that one-way valve! ;)
I guess water always looks to level out, so if the level of the tank is below the pump, the water in the whole system will level out so that there is air at the pump. I suppose it\'s not under pressure so that will be the case, but it doesn\'t explain why it works for other people but not for me! ;)
Wow I never knew those 2 WI systems had so many issues with mounting.
I use a PINZ system made here in NZ. Its a pump that is designed to run dry so you never have to worry about it burning out. The system is run at 100psi & it dosent matter where you put the tank in relation to the pump. The pump is so strong it dosent matter. I have my custom 3 liter rotshaped tank mounted to my fake floor in the boot with the pump next to it. From there the line runs right through under the carpet to the greddy elbow & through the nozel. I have a system 1 so mine communicates with my map sensor & I just turn a little knob to adjust at what boost pressure I need the WI to come on. It kicks in @ 10psi & comes on so strong you can watch the temps on the PFC commander drop like a rock. Other systems can even be set with RPM range to vary the ammount of water & other crazy ****. When the system is not in use the pump just circulates the water through the tank untill you boost. My 3L tank last about 20laps of a 2km track that has 2 very long straights of speeds over 200kph so the WI is working hard.
Iv seen temps on the road as low as 13c & under race conditions 22c. In summer on the way home from work the temps can get up to 30c sitting in traffic, once I get to my turn off all it takes is a blast through 2nd & 3rd to instantly get 15c intake temps.
Im sure your systems do the same thing..its awsome to open the bonnet & feel a plenum thats so cold its like you never even started the engine.
I will post pics when I get home.
Sounds good mate!
I have done some more testing on mine and I can see air in the pipe coming straight from the tank, so I don\'t think it\'s a mounting issue but some air getting in at the seal with the tank. Just need to slap some silicone round it and test for air, hopefully that will cure it!
Also fitted the no-return washer valve but it didn\'t stop the problem. :(
What sort of connections do you guys use? Put up a pic of them.
I will show you my plug & play fittings when I post pics later. Basicly small metal fittings with thread on 1 end sealed with some sort of plastic or silicone based sholder that seals up agains the sholder of what ever you thread it into. On the other side is a receptical that you firmly push your hard plastic type hose into, In side the fitting it grabs the hose & pulls it in. To release it you have to hold back the black tab while pulling on the hose. You will see in the pics.
Yeah, they sound similar to the fittings on my Cooling Mist kit, except they\'re all brass.
Like this?
Pretty much, yep. They\'re not the same, but the principle is identical. I think yours are a bit prettier! ;)
Haha...Cheers.
