Radium Engineering is proud to anounce the release of our newest product, the multi-pump fuel surge tank (MPFST). It is a ground-up new design that can accomodate up to three high performance fuel pumps.
All parts are CNC machined from 6061-T6 aluminum then anodized black for protection from corrosive fuels such as E85.
All components have been weight optimized by removing extra material in the machining process. The bottom plate features integrated "feet" enabling it to mount on uneven surfaces such as a trunk floor. This surge tank is designed to be installed in a vertical position only.
All interfaces are O-ring sealed. The picture below features three internal Walbro 400 E85 pumps.
The surge tank can be configured with one, two or three pumps with a dedicated outlet port for each. Also, each pump has its own dedicated wiring so they can operate independently.
This MPFST is also compatible with other popular pumps from Aeromotive, AEM, Walbro and DeatschWerks. You get to configure it during the purchase. Each one is custom constructed for the order then pressure tested before being shipped.
The new MPFST is shorter (7.8" total height), but larger in diameter (6" diameter) than our existing fuel surge tanks. The working fluid volume of this surge tank when equipped with two pumps is 2 liters.
The pump outlet ports are fixed at -6AN, however the other ports (surge tank feed and return) are sized for -8AN O-ring. -6AN, -8AN and -10AN adapter fittings are optional.
Pricing for this new surge tank starts at $499 (not including pumps)
