Choosing Fuel Line Type and Size
The Bottom Line:
Line Sizes: Choose -8 feed and return for dual pumps systems. We recommend -10 feed / -8 return for triple pump systems.
Line Types: 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)

Fuel Line Sizes
Fuel Line Size for Dual 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.
Fuel Line Size for Triple Pump Systems
-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.
Fuel Line Types
We do not recommend any push-on style hose for fuel. (even the stuff we carry) The barb on push-on hose ends stretches the fuel hose in the direction of failure. Even securing the hose with a hose clamp will not prevent failure, since it does not change the simple fact that the hose is stretched out at the tip of the barb. (failure point) However, push on style hose and fittings are a good low cost alternative for use with lubrication and coolant lines.
FlexLP
FlexLP has the best ratio of pros vs cons than our other hose offerings. Most importantly, its 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.
ADVANTAGES
- Compatible with all automotive fuels, lubricants, and coolant
- Low permeable = no smell when vehicle parked in enclosed locations
- Fast to assemble and install
- Will not contribute to NVH (noise vibration, harshness)
- Soft outer braid will not damage contacted surfaces
DISADVANTAGES
- Expect 5-7 year life
- Requires cable cutter to cut (has internal stainless reinforcement)
PTFE
PTFE is the most resilient to heat and chemicals then 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.
ADVANTAGES
- Compatible with all automotive fuels, lubricants, and coolant
- Infinite shelf and service life
- Non-permeable = no smell when vehicle parked in enclosed locations
- Small outer diameter for AN size = small bend radius, light weight
DISADVANTAGES
- May contribute to NVH (Noise, Vibration, Harshness)
- Stainless braid may damage contacted surfaces
- Expect longer installation times
Startlite
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.
ADVANTAGES
- Compatible with all automotive fuels, lubricants, and coolant
- Easy to cut, fast to assemble and install
- Will not contribute to NVH (noise vibration, harshness)
- Soft outer braid will not damage contacted surfaces
DISADVANTAGES
- Permeable = expect fuel smell smell when vehicle is parked in enclosed locations
- Expect 5-7 year life

-Qty 7, straight AN to ORB fittings
-Qty 2, billet low profile 180 degree o-ring fittings
-Qty 2, -8 ORB 1.25" port extensions

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.
FREQUENTLY ASKED QUESTIONS
Q: Can I use this system with E85?
A: Yes, provided you select our [optional] stainless filter element and select E85 rated fuel pumps.
Q: Should I select the FC2 or FC3 controller?
A: The FC2 will run both pumps full time. Dual small pumps, such as GSS342s may run full time; however, we suggest larger pumps be staged with FC3 due to the heat generated by the large pumps. Please contact us if you need assistance with your fuel pump selection.
Q: Can I purchase the fuel system without fuel pumps?
A: No, since fuel pumps are a wear item and critical to proper operation of the fuel system, we only supply fuel systems with pumps provided by us.
Q: What happens with the original fuel lines?
A: The factory fuel line will be plugged and will not be used in conjunction with our fuel system.
Q: Why doesn't the Fore Innovations fuel pump module have a "basket" surrounding the pumps?
A: The basket is actually becomes a bottleneck in the system at lower fuel levels. The size of the basket is limited by the tank access opening and the depth of tank which is INSUFFICIENT in vehicles that have to ability to consume large amounts of fuel for more than 10-12 seconds. By nature of the dual sump fuel tank design, the pump side of the tank has an adequate sump that provides adequate fuel for your motor. However, considering our fuel system has the ability to transport large amounts of fuel residing in a fuel tank geometrically shaped for smaller pumps, we do recommend you keep at least 1/2 tank of fuel in the tank for racing conditions.
Q: Can I expect fuel smells when the car is sitting or running?
A: Our proprietary hermetic wire seal assures a 100% seal at the wire pass through (we actually seal the outside and inside of each individual conductor). As long as you select our PTFE or FlexLP fuel hose, you can expect fuel smells to be non-existent. Startlite fuel line will smell. Additionally, operating a smaller primary fuel pump will minimize fuel heat and evaporative emissions.
Q: Are Fore Innovations fuel systems noisy?
A: Our module is far more quiet than any external pump. However, please keep in mind that larger pumps make more noise than smaller pumps; likewise, two pumps make more noise than one pump. Generally speaking, our module with a single turbine style pump will be inaudible in the typical customer's car that has an upgraded exhaust system. If you are sensitive to pump noise, we recommend a dissimilar pump setup, using the smallest possible pump for the primary. If you are unsure about pump selection, please contact us.
