I'm preparing to install a Radium surge tank with the Walbro E85 capable 450 pump. (The kit is the MAPerformance kit.) I'd like to be able to control how much fuel the Walbro flows at any given point based on how much flow is required by the injectors. Bottom line is I don't want too much fuel being returned into the system, thus heating the fuel. Sadly, the Radium kit with brushless motors and a motor controller costs upwards of $3500.

TLDR: What is the best fuel pump controller for a Radium surge tank with Walbro 450 pump so I don't flow too much fuel?

Thanks,
Kevin

 

I've been looking at this one. I don't plan on running a surge tank but I wanted to retain variable pump output when I switch to E85.

Interested to see if anyone else has a good suggestion.
