Ok so this arrived in the mail today and will be testing it with the BPM4 fuel controller

Not like we need it but why not I guess as we are running a bucket less setup atm due to the Aussie fuel it supplier stuffing me around for the lass 6 months.

The bucket setup looks real nice and we will be fitting it over the next month or so and will be giving you guys first impression on build quality and ease of install.

Here are some pics.

TI makes Walbro if I'm not mistaken so the pump quality should be fine.

I currently have the radium bucket in the picture installed and have had zero issues with it. Runs twin walbro 450's, stock bucket has stock pump. Twin EKPs. Basically an in tank surge tank set up they developed.

So you have stock bucket and this installed the same time and two ekp modules . Please explain more.

Yes, this goes in place of drivers side bucket. It has a built in fuel pressure regulator and a filter is placed under the car. Their filter comes with a bracket that was well thought out.

If you want to see how the set up works you can jump to their site and pull their diagram.

I'm more interested in how the EKPs are working in your system, which ones and how's the wiring made. I know from Radium's description that they plan on using the stock as a lift pump with OE EKP and have relay(s) for switching on the pumps in their surge tank at the driver side.

Should have clarified

I'm using this with their kit


The dual pump driver

So you have BPM4 and oe ekp, right? How's the wiring done to control both?
This option is under my radar too so that's why I'm curious.

You can't use two ekp's as far as i know.

How we are planning to tackle this is use the bpm4 to run the two pumps in the radium bucket and trigger a relay of one of the pumps to run the stock pump 100% duty cycle feeding the bucket.

BPM4 replaces the OE EKP. Installed it a few months ago and thought I remembered having two EKP's but it was actually one with dual inputs+relays

I have it wired so the lift pump runs when ignition on. It took a few minutes of thought getting wiring done but it wasn't anything too difficult when you have the Radium instructions and the EOS instructions. Both EOS and Radium are prompt on replies so they can help if it doesn't seem clear at the time. Last resort you can always PM me and I can revisit my set up to refresh my memory and help out.

We are going to use a simple relay circuit to trigger the lift pump on/off and only run when the primary pumps are running just like the OE manufacturer intended to, the rest
will be run of the BPM4 and function correctly just the way it should with a dash 8 line going directly to the double barrel where the line will slit into 2 dash 6 lines to feed each pump.

No more fuel starvation when tank gets low.

Ok thanks. So it seems that you have at least two options.
1. To run stock pump with a relay 100% speed and bpm4 to control pumps in radium tank
2. Oe ekp to run stock pump and have relay(s) to run pump(s) (full speed) in radium surge tank

This by far the best commercial setup available, as this basically acts like a swirl pot and upgrades the outlet which is the restriction on the stock setup.
