A strong LS swap fuel line kit pairs a compatible hose and fittings with the length and fuel-pressure setup your conversion requires. EVIL ENERGY 6AN LS Swap Kit 20FT leads this group for buyers seeking a dedicated LS kit with a 58 PSI filter regulator and 20 feet of hose; its listed fuel compatibility excludes E85 and ethanol, so check that limitation first. Other options prioritize PTFE hose, which several listings identify for E85 use, or provide longer hose runs and larger fitting assortments.
Some kits include a regulator, while others are hose-and-fitting packages, so they are not interchangeable without checking your system plan. Compare hose material, stated working limits, included hardware, and compatibility claims before choosing.
EVIL ENERGY 6AN LS Swap Kit 20FT is the strongest all-in-one fit for a buyer who wants a dedicated LS swap line and pressure regulation in one package. The listing specifies 20 feet of 6AN hose and a 58 PSI filter regulator, which makes it especially relevant to builds targeting that pressure. Its important limitation is that the hose is not listed as compatible with E85 or ethanol.
If your fuel requires E85 compatibility, choose a PTFE option that explicitly lists it instead.

View on AmazonAvoid fuel-compatibility and pressure mismatches
Check the exact fuel and pressure requirements before installing a kit; a hose that fits the fittings can still be the wrong choice for the fuel. EVIL ENERGY LS Swap Kit 20FT lists a 58 PSI filter regulator, but its fuel compatibility explicitly excludes E85 and ethanol. Several PTFE listings, including Medoon 6AN PTFE Kit 26FT and BRIFITOR 6AN PTFE Kit 25FT, identify E85 compatibility.
Their pressure figures are not uniform: Medoon lists 3,000 PSI maximum working pressure, while EVIL ENERGY PTFE Kit 26FT and EVIL ENERGY PTFE Kit 20FT list 1,500 PSI. Those figures describe hose limits, not the pressure your engine should receive.
A hose rating does not replace the need for the correct regulator setting, and the regulator’s stated 58 PSI is not a universal LS requirement. Verify both against your system components.
Plan the line run before choosing a kit
Measure the intended route and identify every connection before deciding whether a 20-, 25-, or 26-foot kit will work. The products span those three stated hose lengths, but length alone does not establish fit: routing around the chassis, engine movement, bends, and connection locations all affect the usable run. A long kit may leave extra hose, while a shorter one may not reach the planned route; the supplied listings do not establish a universal LS swap routing length.
Also compare what the package actually includes. Medoon 6AN PTFE Kit 26FT lists quick disconnect fittings and couplers alongside hose-end fittings, whereas other kits list a smaller or unspecified set.
Fittings described as included do not guarantee compatibility with a particular tank, pump, rail, or filter. Check thread types and connection requirements before assembly, and do not assume a supplied adapter replaces a vehicle-specific connection.
How to Choose an LS Swap Fuel Line Kit
Fuel type and hose material
Choose a hose whose listed fuel compatibility matches the fuel you plan to run. The listings distinguish ordinary fuel compatibility from explicit E85 claims: EVIL ENERGY LS Swap Kit 20FT excludes E85 and ethanol, while EVIL ENERGY PTFE Kit 26FT, EVIL ENERGY PTFE Kit 20FT, and several other PTFE kits identify E85 use. That makes the PTFE group the clearer starting point for E85 builds.
For a conventional gasoline or diesel setup where the exclusion is acceptable, the 20-foot EVIL ENERGY kit offers a regulator as well as hose. Do not infer fuel compatibility just from the word braided or from a kit’s LS swap label; confirm the specific product’s stated medium and your system’s requirements.
Hose length and working limits
Match the hose length and stated limits to your planned route and operating conditions. These products offer 20-, 25-, and 26-foot options: the EVIL ENERGY kits at 20 feet suit shorter planned runs, while the 25- and 26-foot kits offer more hose to route. PTFE specifications also vary: Medoon 6AN PTFE Kit 26FT lists a 3,000 PSI maximum working pressure and a temperature range of -76°F to 446°F; EVIL ENERGY PTFE Kit 26FT and EVIL ENERGY PTFE Kit 20FT list 1,500 PSI maximum working pressure and the same temperature range.
The higher stated limit may matter to a buyer comparing hose ratings, but system pressure and temperature must still remain within every installed component’s limits.
Regulator and included hardware
Decide whether you need a regulator in the package or are assembling a hose-and-fitting system around existing parts. EVIL ENERGY LS Swap Kit 20FT specifies a 58 PSI filter regulator; CNRAQR 6AN Regulator Kit also lists 58 PSI regulation and a 10-micron filter, while YEHERIT 58 PSI Regulator Kit pairs a regulator with 25 feet of hose and fittings. For a buyer who already has pressure regulation, a PTFE kit may be the better match: Medoon 6AN PTFE Kit 26FT lists hose-end and quick disconnect fittings, clamps, couplers, and tools.
Other packages list different fitting counts or less detail. Check that the included fittings match your actual connections instead of treating a larger assortment as proof of vehicle-specific fit.
Which LS swap fuel line kit should you choose?
Choose EVIL ENERGY LS Swap Kit 20FT if you want a dedicated LS swap package with a listed 58 PSI filter regulator and your fuel is not E85 or ethanol. For a regulated setup with a 10-micron filter and a 20-foot run, consider CNRAQR 6AN Regulator Kit; choose YEHERIT 58 PSI Regulator Kit if you want 25 feet and its listed C5 Corvette compatibility is relevant. E85 buyers should focus on a kit that explicitly lists E85, such as EVIL ENERGY PTFE Kit 26FT or BRIFITOR 6AN PTFE Kit 25FT.
For a larger documented accessory assortment, Medoon 6AN PTFE Kit 26FT includes quick disconnects, clamps, couplers, and tools. Confirm fuel compatibility, pressure requirements, route length, and connections before ordering.

Frequently Asked Questions
How do I determine the correct fuel-line routing length for my LS swap?
Measure the planned route from the fuel supply connection to the engine connection, following the path the line will actually take. Allow for routing around components and connections, then compare that measurement with the kit’s listed hose length. The listed length alone does not confirm that a kit fits your particular vehicle.
Does my LS swap need a return-style fuel system or a returnless setup?
Choose based on the fuel-system arrangement your engine and vehicle require, not simply on the kit title. Check whether your setup calls for a regulator and how it handles fuel return, then confirm the kit’s listed components match. If that arrangement is unclear, verify it before selecting a kit.
What fittings or adapters will connect the kit to my fuel tank and engine?
Compare the kit’s listed fittings and adapters with the connections on your tank and engine. These products use 6AN or AN6 components, but titles alone do not establish that every connection will match your setup. Confirm the required adapter types and connection sizes before ordering.
Which kits explicitly list E85 compatibility?
The listed PTFE options that explicitly identify E85 compatibility include EVIL ENERGY PTFE Kit 26FT, BRIFITOR 6AN PTFE Kit 25FT, and the other product titles specifying E85. The EVIL ENERGY CPE kit does not list E85 or ethanol compatibility. Verify the exact listing before choosing fuel-line material.
How should I choose between kits with different hose lengths and regulators?
Match the listed hose length to your measured route and the regulator details to your build’s pressure requirements. The EVIL ENERGY dedicated LS swap kit lists 20 feet of hose and a 58 PSI filter regulator; CNRAQR lists a 10-micron filter and a 20-foot run, while YEHERIT lists 25 feet and 58 PSI.
Final Words
For a dedicated LS swap package with a listed 58 PSI filter regulator, the EVIL ENERGY 20-foot CPE kit is the clearest fit when your fuel is not E85 or ethanol. If you need E85 compatibility, select a PTFE kit that explicitly lists it. Before ordering, verify route length, pressure needs, fuel compatibility, and connections; consider CNRAQR or YEHERIT when their listed regulator details better match your setup.
