Alright guys who has them on a X and what does it consist of? I have done searches and know MAP offers a kit, I have seen custom Radium setups, but other than that not much. I need this due to fuel starvation while on road courses, worse since switching to E85. Thanks!

I already have two Walbro 450 E85 pumps.

 

Maybe a vendor could chime in?

 

What do you need two wally 450's for?

Run wally 255/AEM 320 in tank feeding a radium surge tank. Either buy the kit from MAP for mounting behind the bumper or use Radium's mounts and put it in the trunk and do a homebrew.

 

Got a deal on the Walbro's and have not had good success with the Aero 340's, on my second one and that one is now having issues. At some point I may run a T4 Borg Warner setup on a 2.2 or 2.4 and will need more fuel (FIC 1100's and Aero 340 are 100% IDC at 26 PSI on E85 already). Agree with your recommendation and that is what I have been considering. I was just hoping there may be a few others doing different and have a couple options.
