What are the benefits of a fuel braided fuel line?
It also delivers extended service life in any fuel as it will not harden, micro-fracture or permeate fuel vapor (vapor-walk) like normal rubber braided line, minimizing fuel smell in the vehicle storage area.
What is the difference between PTFE fuel line and rubber braided fuel line?
PTFE fuel line provides outstanding flow capacity, is smaller on the OD for the same ID of a comparable rubber braided line for easier routing in tight spaces.

Can you use braided line for fuel line?
Aeromotive PTFE Stainless Braided Fuel Line is ideal for street and racing applications where E85, gasoline or methanol compatible fuel line is needed. The stainless steel outer braid provides impact and abrasion resistance and protects the PTFE inner liner.
What size fuel return line should I use?
The Fuel Return Line should be at least the same size, or one size larger than the supply. Make sure there are no sharp bends or kinks. The return line should direct fuel close to the bottom of the tank and away from the pickup.
How much horsepower will a 3/8 fuel line support?
A 3/8”id fuel line can easily support 600 HP given sufficient “pump head”! Given a big enough pump a 3/8” steel line could support 1000 HP. The simple way to know is to install an electronic fuel pressure gauge. If the pressure falls as the engine RPM's go up you need more pump head.
Are braided fuel lines safe?
Modern fuels have additives that harden and deteriorate traditional rubber hose including stainless steel-braided hose. This leads to potentially dangerous leaks and weeping.
What is best material for fuel line?
The best fuel line material depends on your needs. However, the best material for fuel lines is polytetrafluoroethylene or PTFE. PTFE fuel line is made of plastic material specifically known as Teflon. This fuel line material is impervious is resistant to the degenerative fuel effects which could form vapor barriers.
Is a shorter fuel line better?
A larger diameter is generally better, but the correct diameter is the best choice. If the diameter is too small: you won't be able to support your horsepower goal. If the diameter is too big: the lines will take longer to pressurize.
Does size of fuel line matter?
Does size really matter when it comes to fuel lines? According to the fuel delivery system experts at Fuelab, it does. It's because fuel line size and length have a direct effect on the amount of fuel pressure drop your fuel system will experience.
Does fuel line size affect pressure?
Shows the relationship between measured pressure drop as a function of flow rate, for four different fuel lines (two different sizes at two different lengths). Every fuel line experiences pressure loss depending on fuel line length, and fuel flow rate.
Does a Holley Blue fuel pump need a return line?
Fuel pressure is pre-set at 15 PSI and both a pressure regulator and 3/8" return line to the tank are required.
Do you need fuel return line?
Return-style systems require fuel pumps to work all the time—it never shuts off as long as the engine's running, which can shorten the life of the pump. Your plumbing system can become more complicated because you have to run a separate return line from the regulator to the tank.

Where to put 100 micron fuel filter?
We recommend you install a 100 Micron In-Line Fuel Filter between the tank and the pump.
Why do you need an external fuel pump?
However, when using an External Fuel Pump, you can starve it for fuel if the line is too small.
What size fuel line is used for Aeromotive?
Aeromotive PTFE Stainless Braided fuel line is available in standard sizes including AN -06, -08, -10 and AN-12, and comes in pre-cut lengths (from 4-ft, 8-ft, 12-ft up to 16-ft).
What is PTFE fuel line?
Aeromotive PTFE Stainless Braided Fuel Line is ideal for street and racing applications where E85, gasoline or methanol compatible fuel line is needed. The stainless steel outer braid provides impact and abrasion resistance and protects the PTFE inner liner. Aeromotive’s PTFE liner is specially carbonized for conductivity, which is critical for fuel handling. This product is not legal for sale or use on emission-controlled vehicles except when used as a direct replacement part matching OEM specifications.
Is PTFE liner legal for sale?
Aeromotive’s PTFE liner is specially carbonized for conductivity, which is critical for fuel handling. This product is not legal for sale or use on emission-controlled vehicles except when used as a direct replacement part matching OEM specifications.
How to determine fuel line size?
The size of the fuel line is determined by the outside diameter. Completing the measurement is simple and takes relatively few tools. The same steps can be used to measure other types of tubing, such as those for brake lines.
How to measure distance between two sides of a fuel line?
Calipers are used to measure distance between two sides of one object. Adjust the tips of the caliper to fit tightly on either side of the line. Remove the caliper. Place the tips on a ruler and read the measurement.
Why is it important to know the size of the fuel line?
It is important to have the right size so the vehicle operates efficiently.
Can you disconnect a fuel line?
Uncover the fuel line so that it is visible and can be reached easily. Do not remove the fuel line or disconnect it.
How often should you check fuel lines?
You should check fuel lines, connections, and fuel vents at least twice a year. If you notice any leaks, you need to fix them before starting and driving the vehicle due to the fire hazard that could result from use.
How to fix a leaky fuel line?
Ideally, to fix a fuel line leak, you should replace the line or seals if it has them. If the line is rubber it will need to be replaced. If it is a hard line, there are a few options. If there is a break in the line that isnât on the end, and it is low pressure, you can use a compression fitting . This works by cutting the line, cleaning the two ends created from the cut, and rejoining them together with the union. You can also use a flare tool to add tubing nuts or fittings and create a new connection. The third option, while not ideal, is to cut the line, flare the ends, and connect them with a rubber hose, using good clamps. This only works with low pressure applications. If possible, upgrading fuel lines that leak with performance fuel lines will offer a much safer and longer lasting connection.
What to do if fuel line disconnect tool is not available?
If a fuel line disconnect tool is not available or an option, you will need to make a tool that would match the shape and curve in order to get it to fit the connector. The tool will have to be able to slip between the connector and line in order to disconnect it.
What is the AN number on a hose?
The AN numbers refer to the tubing OD in sixteenths of an inch. For example, 8AN hose has the same ID as a 1/2" nominal tube (8/16 = 1/2). 3AN hose has the same ID as a 3/16" tube. This means that 6AN hose will not introduce any appreciable flow restriction in a fuel system designed around 3/8" OD rigid tubing.
Why is ordering plumbing fittings confusing?
Ordering AN plumbing fittings can be confusing because the nomenclature does not directly translate into a thread size. Fortunately, each AN size will always correlate with one specific fitting size. There are no exceptions, so there is no guesswork. Measure the thread OD and pitch, and you know the fitting size.
What gauges are good for go no go?
Tip: If you don't have a proper measuring tool handy, open-end wrenches make great "go-no go" gauges in a pinch! If a 7/16" wrench slips over the threads but a 3/8" wrench doesn't, you have a 4AN fitting.
Can you thread a 10AN hose end on an 8AN?
If you compare the male OD in the first table to the female ID in the last table, you will note that (with the exception of 3AN and 4AN), no two AN sizes are even close enough to start threading together. If you try to install a 10AN hose end on your 8AN male fitting, they won't cross-thread or even "almost" fit together. The 10AN male will literally drop over the 8AN fitting and then fall right off.
Can you assemble AN fittings?
As long as you are dealing with AN fittings, a proper fit will be obvious and a mismatch will be impossible to assemble.
Is 5AN hose rare?
While a specification exists for 5AN hose and fittings, it is exceedingly rare in the aircraft industry. Even manufacturers specializing in AN-style fittings strictly for motorsports tend to skip over the 5AN size for the most part.
