You've probably seen or heard of Sai Li Tuning and Racing in recent times, given that they've been involved with a lot of 7-second and 8-second Mustangs, including Donnie Gilder's 4000-lb S550 dubbed "The Unicorn."


The same quality and precision that's put into their tunes can be found in LTR's Fuel Pump systems for S197 and S550. LTR's system is capable of handling up to 1000rwhp and its modified GT350 pump assembly is an OEM fit compatible with the OEM feed line for easy installation. Using an Aeromotive regulator, excess fuel is bypassed after supplying the rails, and then returns to the pump assembly. 


Product Benefits:

  • Dual-pump return style fuel system
  • OEM fit for easy installation
  • Supports up to 1,000 rwhp
  • E-85 compatible
