This deep well acts as a small surge tank. The return fuel goes here and there is a one-way valve at the bottom that draws fuel in but doesn’t let it drain out. These features help reduce the chance of fuel starvation in hard cornering, acceleration, or braking.
To keep things simple, we are running a single Walbro 422 LPH pump with our Radium hanger. The pump has a dual-channel turbine design which features a single impeller with two parallel rows of turbine blades. The blades feed two high-pressure pumping channels, as opposed to a conventional single-stage pump that uses an impeller with a single row of blades at its outer edge. This results in improved hot fuel flow, as well as minimal noise and current use, resulting in efficiency that’s 20 percent higher than conventional pumps. All pumping components have been validated to OEM specifications for approved use in E85/flex-fuel applications.
As EJ engines tend to have a lot of crankcase pressure and create a lot of oil-filled blowby. During a few laps on the track, they can blow a sizeable about of their oil out of the breathers. We are using an IAG self-draining air-oil separator to solve this issue. We did a video on how this works here!
EJ engines don’t have the best oiling, to help this we are installing IAG’s high volume, high-pressure oil pump.

Love all the updates, and that its all finally coming together!
One word of caution is any pitch stop mount, from the aftermarket, seems to just perfectly resonate the factory firewall.
If you have the chance getting a good CLD layer in and as high up as possible on the firewall surrounding that immediate area in-cabin, opposite the mount will make a dramatic difference in reducing NVH. If only 50% of the firewall were covered, that is enough. e.g. 4-5sqft total. Minimal weight added, but very targeted to that part. SecondSkin, Resonix, Dynamat Extreme are all good examples of quality CLD tiles that can handle heat and not put off a strong smell.
Can’t wait to see this all come together. Best wishes for reliability and longevity. HP per dollar spent be damned lol
Any picks of install of the COBB’s Overflow Tank and Washer Reservoir filler? I am interested in that kit and install.
