WHY DO I NEED A FUEL SURGE TANK?

Shown below is an 18 minute track session of our Lotus Elise without a fuel surge tank installed.

X Axis: Fuel Pressure above 1500RPM Note: Pressure SHOULD be ~47.5psi constant 

Configuration 

The Frame Rail Mount (shown below) was designed for 2004-up Lotus Elise/Exige models with a nonsupercharged 2ZZ-GE engine. This location is compatible with A/C equipped cars and is ideal if the clamshell is modular. However, for the OEM supercharged Elise/Exige, Lotus relocated the emissions charcoal canister to this area. The charcoal canister will have to be removed or relocated if this FST location is necessary. Note: Lotus Cup Cars do not use a charcoal canister so the Frame Rail Mount option is viable. 
 
The kits come with a billet fuel filler adapter (shown below) that is suitable for the Elise and Exige.

If installing into the rare Lotus Cup Car or Lotus 211, Radium Engineering 14-0062 will need to purchased separately. This is a larger billet fuel filler adapter that is compatible specifically to these vehicles.
