Why Go In-Tank Instead?

Quieter, Cooler, More Reliable

  • Pump runs submerged in fuel for lower noise and longer life
  • No external pump hanging off the frame rail
  • Reduces vapor lock and fuel starvation under load

Retrofit Your Existing Tank

  • Universal modules fit most tanks
  • Adjustable pump height for a range of tank depths
  • No need to replace your entire fuel tank

Return or Returnless. Your Call.

  • Standard modules run with a return line to the tank
  • Regulated modules include a built-in 58 PSI regulator
  • Returnless single-line setup available for cleaner installs

Ditch the External Pump.

An external fuel pump bolted to the frame is loud, exposed to heat, and prone to vapor lock. An in-tank pump sits submerged in fuel where it runs cooler, quieter, and with a steady fuel supply. FiTech Go Fuel in-tank retrofit kits drop into your existing tank and deliver the high pressure fuel your EFI system needs. No new tank required. No external pump cluttering up the engine bay. Just clean fuel delivery from inside the tank.
