fuel starve solutions

This would of course not be possible without some form of surge protection.

As time goes on, we will find out more what its capable of. Higher power (fuel consumption rate) is asking more from it, more aggressive back and forth sloshing is asking more of it. It will be interesting to see where the limit is, or if anyone finds it. But I think its safe to say at this point that the canister add-on for the twin pump has the fuel slosh issue well under control.

Even if a limit is found beyond what its been through so far, it is still a world of improvement already and should be all that most users need. On top of that, I have one more add-on for the twin pump coming. Its a multi-point scavenging kit that is going to scavenge fuel from the remote corners of the tank. With this final addition, there is not really much else to ask from a fuel pump system.

The only reason to proceed with the RRP2.0 is to have something for people who dont want to install a return system, primarily naturally aspirated track cars. But the RRP2.0 will still be setup to accommodate big power and return systems anyway, because people are known to change directions with their build.

I was reading through this user's experience with the Radium kit - not sure if it applies to your system, so i apologize in advance:
Radium Fuel Hanger Surge Tank and Akebono upgrades, installed by Enthusiast Auto Care

Two issues that caught my attention:

The installer noted a need to upgrade the wiring to accomodate the draw from the aftermarket pumps. I was reading through some of the literature on Radium's website (as a total notice), and it appears there is a pretty obvious relationship between the power draw and the flow ability , although some can be more efficient than others. Will your system need upgraded wiring, and if so, will it be provided?

Also, this user noted some inaccurate fuel readings after installation; the car would show near empty when there was still over a gallon and left or so. IS this an electrical thing, and an issue that can be avoided?

Thanks for your work man!
