Radium Fuel Basket vs Verus Fuel Flap
 
Does anyone have any experience with both?

Thoughts?

I beleive I am having fuel starvation issues (Stock NA FA20) on track. I will likely just use the Verus flapper door to start, but would consider the radium fuel basket.

Radium fuel basket is a slightly larger area within the pump and still relies on a 1-way check valve to fill the basket, but either system will still encounter fuel starve issues depending on slosh.

The positive aspect of the Radium offering is it can take a return line from a return-type fuel system to fill the basket as priority, so unless you're going with a surge tank offering IMO it would work better than the Verus Flapper, but you'll still run into issues.

I had predictable fuel starve situations at certain tracks/corners once I was e85, aero, sometimes hoosiers. The typical problem. I found the Verus flap did help but was still overcome at times. My solution was adding a submerged low pressure pump to the right side of tank with hose feeding the primary pump basket. This has completly solved the problem for me. No issues running level down to 1/8th. I think I spent $50 or so.

I think the one benefit to the Radium tank would also greatly become more beneficial when used with a lower pressure pump, since it would input directly into the 1-way check valve fill basket

I've been using the Verus Fuel Flap for quite some time, and it completely solved my fuel starvation issues—it's been working like a charm. My FRS is a naturally aspirated stock setup with no aero, prepped for the track and running on 200TW tires.

Verus Flap Ordered -- Once installed I'll report back

I went with the GKTech flapper on mine and so far I have nothing negative to report.

I had a BF deal and I was boosting my car so I had a "save every penny" thing going on in my head. I like Verus stuff and have a good bit on my car but my cheapskate nerve kicks in every now and again.

Are you powering that separately or tied into the OE fuel pump power connection?

On its own fused relay with a dash switch so it not constantly pushing fuel to the drivers side. You have to run wires thru the top of the sender cover anyway

Kinda the direction I was going to take. I didn’t know if the stock fuel pump controller could handle two pumps at once. I was going to run dash switch with relay to a small PWM motor controller since I don’t think I will need full beans on the secondary pump to keep it from starving.

That should do it
