With the ever growing progression of horsepower, SPE Motorsport thought it was time to give the mustang guys some more power capability. It's not uncommon for GTR’s and Lambos to produce well over 2000 hp. The domestic market is used to needing mechanical fuel pumps or extremely high dollar electric pumps and control modules. Now there is a simple effective drop in solution. 

SPE is proud to introduce our solution, The Tetrad Fuel Pump Module (FPM). This fuel pump module holds up to four 525LPH pumps or any other 39mm diameter pumps making the Tetrad capable of supporting 2400+hp on E85.

The Tetrad is designed in a way to easily fit 4 pumps in the factory S197 and S550 tanks and utilizes the siphon just as the factory system does for the saddle tank. The factory sending unit also clips right on for a simple install.  SPE Motorsport also wanted it to be as adaptable to the customers needs as possible, allowing for multiple types of pumps and quantities. It was also designed to allow for the you to grow into it if needed. This allows you to start with 1-2 pumps and later be able to an addition 1-2 more.



  • Patented Gland Seal- Wiring passes through a patented gland seal that allows wires to be added and removed with ease. The gland form fits the wire and compresses when the top flange is bolted down. Unlike bulkhead pass through fittings which are bulky, not serviceable and hard to fit. These hermetic seals don't allow you to service the wire and/or add pumps later on. The gland seal gives the customer the best of both worlds a great seal and serviceability.
  • No Brackets or Hoses- The Tetrad is completely billet with no brackets or hoses. The fuel pumps are held by an O ring isolated in a billet housing which dampens noise and allows for easy adjustment.
  • Fuel Plenum- The siphon circuit of the pump is pressurized by the fuel plenum in the module. This means the pump positions used have no effect on the siphon circuit unlike other fuel pump hats that create siphon off of one specific pump position. In those systems if the primary pump is not in the correct position it may not siphon properly. This is not an issue with the Tetrad FPM. As long as there is a pump on, the siphon will function.
  • Anodized- The Tetrad is fully anodized to resist corrosion from E85 and other corrosive fuels.¬†
