Recently redesigned for 2019, the Radium Engineering MPFST is the perfect solution for high power vehicles experiencing fuel starvation during aggressive driving. Up to 3 high flowing fuel pumps can be used in the surge tank.
Because all of the compatible pumps utilize an integrated check valve, the MPFST merges all pumps into a single outlet simplifying external plumbing. This "PUMP OUT" port is 10AN ORB threaded but comes preinstalled with a -8AN male adapter fitting. The "OVERFLOW", "SUPPLY", and "RETURN" ports are all 8AN ORB threaded but come preinstalled with -6AN male adapter fittings. All of these fittings can be swapped out with different sizes (sold separately).
When fuel enters the MPFST through the "SUPPLY" and "RETURN" ports, it gets redirected and runs tangential through the canister creating a swirl pot. This helps eliminate unwanted air bubbles and fuel foam that can affect fuel pump and engine performance.
The pumps are mounted using an anodized aluminum bracket. All internal wires are gasoline, ethanol, and methanol compliant. Filter socks have been replaced with a stainless steel mesh inlet screen. The pump power connections are handled with specially designed high-current electrical studs.
The underside of the MPFST is suitable for uneven surfaces commonly found in the trunk of a vehicle. Necessary ring terminals and hardware are included with every surge tank. Stainless steel M6x1.0mm socket head bolts are included for custom mounting.
