High Horse Performance is Veteran Owned & Operated

Boost Referenced Return System for 1800+ rwhp. Regulator mounted before rails. (pre-regulated) Parallel feed to fuel rails, with plug on end of each rail. We generally do not recommend this configuration since fuel vapor is trapped in the rails during starting and the fuel density may be inconsistent due to fuel stagnation.


  • Cherokee WK2 Fuel Pump Module (triple pump)
  • F4i Fuel Pressure Regulator
  • FCV Checkvalve
  • 88mm Inline Fuel Filter
  • Billet Hellcat Hemi Fuel Rails

All fittings, hose, hardware required for typical fuel line plumbing

-30 feet of fuel line and 10 matching hose ends (your choice)
-Qty 6, billet low profile 90 degree o-ring fittings
-Qty 4, straight AN to ORB fittings
-Qty 3, -8 ORB plug
-Qty 2, -8 ORB 1.25" port extensions
-Qty 10, hose straps and mounting screws

Notes on Hellcat OE Fuel Pressure Sensor Options:

By default, our fuel system will delete the OE fuel pressure sensor. Due to popular request, we have added the following provisions for the fuel pressure sensor, which must be selected by the purchaser:

  • Delete OE Fuel Pressure Sensor
  • Inline Aftermarket Sensor: includes a new AC Delco sensor and provisions to mount in a high flow coupling with two more hose ends. In L2 and L4 systems, this can be installed without extending the OE electrical harness; however, extension of the OE harness may still be required on L3 systems.
  • Regulator Mounted Aftermarket Sensor: includes a new AC Delco sensor and an adapter to mount directly on the fuel pressure regulator. The installer will have to extend the OE electrical harness to accommodate the new location of the sensor.

Choosing Line Size: Choose -8 feed and return for dual pumps systems. We recommend -10 feed / -8 return for triple pump systems.

  • We suggest -8 feed and return in any dual pump setup, simply because there is no measurable benefit to running a -10 feed with any dual pump fuel system. However, selecting a -10 feed is a good choice if you're planning to possibly upgrade to a triple pump system later (via our triple pump upgrade program). Of course, it is possible to run a -8 feed and -6 return; however, most of our customers find the fuel system installation is more flexible when all the fittings are the same size.
  • We suggest -10 feed and -8 return lines allow any triple pump system to operate without restriction. However, -8 feed/return may be used if you're running three small fuel pumps (i.e. GSS342) or if your fuel system choice was marginal over whether to choose a dual or triple setup. So, if you're making 1100 rwhp on E85 (which is possible on a dual pump setup if your build is very efficient) but you chose to go with a triple pump setup, we would suggest a -8 feed/return since you don't need every ounce of performance out of a triple pump setup.

Choosing Fuel Line Type: FlexLP vs PTFE vs Startlite

Startlite will emit fuel smell and should only be used on cars kept outside or in detached garages/shops. Cars kept in attached garages should use FlexLP or PTFE, which will not emit a fuel smell. PTFE has a stainless outer reinforcement and will last forever, whereas FlexLP has a soft black/gray nylon outer braid and some insulating properties. (no NVH and more friendly with fuel pressure sensors/gauges). Our preference is FlexLP since it is much easier to work with as compared to PTFE which is not flexible.

  • FlexLP has the best ratio of pros vs cons than our other hose offerings. Most importantly, it's low permeability prevents fuel vapor smell when the vehicle is parked in closed areas. Cosmetically, some of our customers prefer the black outer braid over the stainless braid of PTFE.
  • PTFE is the most resilient to heat and chemicals than any other fuel line we offer, and likewise can be expected to outlast the vehicle. The PTFE core cannot be permeated by any fuel, and therefore will not emit a fuel smell when the vehicle is parked in closed areas. Cosmetically, some of our customers prefer the look (or contrast) of the stainless outer braid.
  • Startlite is race hose, and therefore we only recommend it for vehicles that are stored outside or kept in a detached garage or shop. Fuel can permeate the lines and will usually emit a fuel smell in the storage area.
