Lethal Performance Tech Tips: Fuel System Series
Episode 4: P.T.F.E. vs Push-Lite Fuel Hose
When you go to buy a fuel system on our site, one of the drop down options is to choose the type of fuel hose you would like the system to come with.
There are 2 options:
We are often asked what the difference is between the hoses and if one is better than the other. In Episode 4 of our Fuel System Series, Jared discusses the answer to those questions!
Let’s start with the Push-Lite Hose, aka push lock. This hose consists of an inner layer of synthetic PKR covered with a fiber braid reinforcement and wrapped with a weather-resistant textile cover. It is very flexible and comes in sizes from 4an to 12an.
Episode 4: P.T.F.E. vs Push-Lite Fuel Hose
When you go to buy a fuel system on our site, one of the drop down options is to choose the type of fuel hose you would like the system to come with.
There are 2 options:
- Standard Pre-assembled Fragola PTFE Hose
- Fragola Push-Lite Race Hose and Fittings

Let’s start with the Push-Lite Hose, aka push lock. This hose consists of an inner layer of synthetic PKR covered with a fiber braid reinforcement and wrapped with a weather-resistant textile cover. It is very flexible and comes in sizes from 4an to 12an.
The fittings used are a simple barb fitting that is pushed onto the end of the hose (hence the name) and can be further strengthened using Fragola clamps (https://www.lethalperformance.com/shop-now/vehicle-selector/ford-mustang-v8-gt/2015-2017-ford-mustang-gt/fuel-delivery/fuel-hose-1/stainless-steel-band-clamps-1']click here[/URL] for the clamps).
Check out this (super old) video of [baby] Jared installing a Push-Lite hose end onto the hose:
We have used this hose in many of our project vehicles, but when E85 started hitting the market we noticed that the fuel would permeate the hose and create a fuel smell (fuel weep!). We weren’t happy with this (and neither were our customers) so we reached out to Fragola for a new alternative. They obliged with their PTFE series of fuel hose.
The properties of P.T.F.E. make it a natural for all highly corrosive applications like E85 and other ethanol fuels. The hose will take high pressure and cycle over and over without failure.
P.T.F.E. powder is extruded into a smooth bore tube product. The tube is then fed into a machine that weaves stainless wire into the familiar braided pattern. The hose is then coated with a protective black coating that not only functions as a barrier but also looks super clean.
Unlike the push lock setups, all of our fuel systems ordered with PTFE hose will come pre-assembled with the fittings installed. We have diagrams outlining the placement of the hoses on our Installation Instructions pages for the systems (https://www.lethalperformance.com/info/customer-service/installation-guides']click here[/URL]), making it easier for you.
NOTE: Our 99-04 Budget systems will come with 1 fitting not installed (pictured above), as each car & setup will require the line to be a different length. However, you can install the fitting yourself with basic tools & some elbow grease.
If you have any further questions on which fuel hose is best for you, give us a call and we'll be happy to help (877-2-LETHAL or 561-753-8105). You can also shoot us an email at support [at] lethalperformance.com!
Stay tuned for future episodes of our Fuel System Series where we’ll go over more components of the return style fuel system.
