After the success of our first & second generation surge tanks, we have updated the design even further with more features and a better overall finish.

Check out some of the features below...

TAARKS "ST" series of surge tanks have been designed to meet the demands of performance vehicles from around the world! For this reason we have design protected the special features of our tanks (Design Number: 201412624)

We offer a single pump "ST-460" and a twin pump "ST-920" *The single pump version is fully upgradable to a twin pump setup at any time.

Our surge tanks utilise the High Pressure Walbro 460 or Walbro 525 fuel pumps, these pumps truly are in a league of their own and can support 700+HP worth of fuel each for the 460's and 900+Hp worth of fuel each for the 525's!

Our unique round design with machined top and bottom plates eliminates ANY trapped air pockets, unlike square tanks.

Now a 3 piece design means no more welds, allowing for a much nicer overall finish.

**100% E85 Compatible.
