Specifications, compatibility and supplied components
Product details
Radium Engineering Fuel Surge Tank for Ti Automotive E5LM Pumps is a high-flow fuel surge tank designed to help prevent fuel starvation on high-power road, track and race vehicles.
The MPFST uses fuel supplied by the vehicle's lift pump and returning fuel to maintain a buffered supply to the high-flow surge-tank pumps. This helps maintain fuel delivery when the main tank experiences fuel slosh or temporary starvation.

- Can accommodate one or two pumps
- Swirl-pot design helps reduce air bubbles and fuel foam
- 10AN ORB pump-out port with supplied 8AN adapter
