Kev.O Posted December 11, 2007 Share Posted December 11, 2007 I've bought the HFS-5 and looking for options of where to mount the pump and water bottle. As the new pumps are alot larger than the old style ones, I'm considering installing it in the boot along with the water bottle. Will this cause any problems ie lower pressure when the water reaches the jets/will the pump have to run harder in order to pump the water further (thus reducing the life of the pump)? Has anyone other than Tricky installed the pump and bottle in the boot? TIA Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted December 11, 2007 Share Posted December 11, 2007 If that is the system that uses the HSV then you have nothing to worry about by putting the pump/tank in the boot as the pump will just maintain pressure, its not like it has to keep up with the HSV as the pump is more than capable of providing enough volume, if you want to add a primer pump it will help flow even more, i just use a washer pump run from the DDS3 trigger.

Kev.O Posted December 11, 2007 Author Share Posted December 11, 2007 Tricky, did you run your water line under the car like the manual recommends? I was thinking of running it next to my new fuel line. I'll take an extra pair when I put the cabling in, so I have the option of a primer pump.

Tricky-Ricky Posted December 12, 2007 Share Posted December 12, 2007 No, mine is straight through the cabin and into the engine bay, its quite easy, apart from that i have never seen a manual that says anything about running it underneath the car.

Kev.O Posted December 12, 2007 Author Share Posted December 12, 2007 The manual refers to 'applications involving methanol mix beyond 50%'. I knew I read it somewhere though it isn't relevant in my case . Did you run the line along with the power cable? As I have the brake and fuel line covers off, are there any disadvantages of running it under the car? Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted December 12, 2007 Share Posted December 12, 2007 Should be fine as long as you are running some methanol. Quote Link to comment Share on other sites More sharing options...

b_have Posted December 12, 2007 Share Posted December 12, 2007 It will freeze if no meth. I mounted my tank where the charcoal cannister was. Quote Link to comment Share on other sites More sharing options...
Kev.O Posted December 12, 2007 Author Share Posted December 12, 2007 It will freeze if no meth. I mounted my tank where the charcoal cannister was. Ahh ok. I've already got a few things fitted there. It's hard trying to find somewhere to mount the pump as it's so large Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted December 13, 2007 Share Posted December 13, 2007 The pumps don;t like high temps and may trigger thermal cut out if you mount under the bonnet. Quote Link to comment Share on other sites More sharing options...

Dick will this bottle be suitable for the install? I should be able to use the motor as a primer pump right? Quote Link to comment Share on other sites More sharing options...
tooquicktostop Posted January 3, 2008 Share Posted January 3, 2008 Dick will this bottle be suitable for the install? I should be able to use the motor as a primer pump right? I purchased a proper water injection alloy tank with foam inside to prevent surge causing intermitent flow, I found several on ebay and in Demon Tweaks, I am having my Aquamist fitted into the boot also, and wanted a larger tank capacity and cooler position Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted January 3, 2008 Share Posted January 3, 2008 Dick will this bottle be suitable for the install? I should be able to use the motor as a primer pump right? It should be fine, but you will need to check the level frequently, and yes you can use the pump as primer pump, it powers from DDS3 v8/box, i have used a 5lt water carrier from a camping shop, works fine, and no surge problems if kept at a reasonable level, and apart from that a primer pump will stop surge anyway.

I must admit the capacity did worry me a little. Having the pump already fitted is a bonus though. Quote Link to comment Share on other sites More sharing options...

Kev.O Posted January 6, 2008 Author Share Posted January 6, 2008 Rather than starting a new thread, I thought I would ask a question in this one. It shows in the manual the power for the DDS3 coming from the ECU, is this ok as it's protected by a 3.15 amp fuse so I'm assuming it's going to pull a little bit of power.

Kev.O Posted January 7, 2008 Author Share Posted January 7, 2008 I thought I would post up a picture of where I intend to mount the flow sensor. I made up a plate for several of my parts to be mounted on to keep them all in one place and tidy. I put the heat shrink on the tube incase it rubs against the edge of the DLI.

Kev.O Posted March 16, 2008 Author Share Posted March 16, 2008 I've ran two extra cables into the boot of my car so I can use a priming pump. Two questions, can anyone recommend a decent priming pump that uses 6mm ends? And the other question is, where should I wire the ground and positive inside the DDS3 JB? Many thanks.

Kev.O Posted March 16, 2008 Author Share Posted March 16, 2008 I was wondering whether this would work though it doesn't say what size pipework attaches to it Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted March 17, 2008 Share Posted March 17, 2008 That should be fine mate, i think most pumps have 6mm spigots, as for DDS3 I'm not quite sure what what you mean, the gauge or the junction box? Quote Link to comment Share on other sites More sharing options...

I mean where do I connect the additional wires inside the Junctin Box? Quote Link to comment Share on other sites More sharing options...
Kev.O Posted March 18, 2008 Author Share Posted March 18, 2008 After having a read on the waterinjection website, I now realise that I don't need to connect the primer pump wires in the junction box itself as the output is only rated at 0.25amps. I'm guessing I just run the primer pump in parallel with the ERL pump, cutting into the wires after the relay? Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted March 19, 2008 Share Posted March 19, 2008 Sorry forgot about this, i will have to check, but i think you do use the DDS3 junction box, but AFAICR the box provides a negative trigger for the primer pump, you just wire it with a + feed, but i will double check mine for you later.
