Are fuel lines heat resistant?
Fuel line is a petroleum-resistant nitrile tube with a covering that resists weathering, ozone and heat and can be used for ethanol-laced fuels and diesel fuel. It should, however, not be used on coolant systems, oil systems or fuel-injection systems that produce pressures higher than 50 psi.
Is marine fuel line different?
As I understand, one big difference is better UV resistance in the marine fuel line. Automotive fuel line gets a virtually no exposure to direct daylight, so little to no need for UV protection. Another possible difference is better flame resistance in the marine fuel line.
Is fuel line measured ID or OD?
Tubing is OD (outside diameter) and Pipe is ID (inside diameter). So the easiest way to tell the size of your fuel line, which is tubing, is to use a combination wrench. Whichever one slips over snuggly is the winner.
How much HP will 6an fuel line support?
at 45 psi for engines producing up to 870 hp naturally aspirated, or 725 hp forced induction. Its rated at 70gph free flow and a max psi of 65psi. Yes there is a big difference at 40psi and 6.5psi but its all about volume.
Which fuel line is the return line?
The vapour-return line normally runs from the fuel pump or the fuel filter to the fuel tank. This vapour-return line is connected to a special outlet in the fuel pump. Any vapour that forms in the fuel pump returns to the fuel tank through this line.
What is the best material for fuel lines?
The best solution is a material called PTFE. That stands for polytetrafluoroethylene—a plastic material that is best known as Teflon in one specific variation. This material is impervious to the degenerative effects of fuel that also creates a vapor barrier so fuel vapors cannot leak past.
How long does marine fuel hose last?
10-15 yearA reasonable time frame would be the 10-15 year mark. Ethanol which found its way into marine gas in the mid 90s is why your hoses need to be upgraded. The fuel filters will keep the debris out but there is a black sludge that reforms in the carburetor causing the passages to get blocked.
How do you determine pipe size?
Measure the Outside Diameter (OD) of your pipe or pipe fitting:Wrap a string around the pipe.Mark the point where the string touches together.Use a ruler or measuring tape to find the length between the tip of the string and the mark you made (circumference)Divide the circumference by 3.14159.
Is 3/8 fuel line big enough?
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 gage. … More pump head can be achieved with a bigger pump, higher pump voltage and/or increasing the line size.
What size is boat fuel line?
Of course, the 3/8″ fuel line will work for any of the outboards. But most smaller outboards have fittings or quick connects on them that are set for a 5/16″ hose. It’s basically the standard hose for the smaller engines.
Can a fuel line be too big?
Going nowhere fast. However, in fuel line we are talking about diameters in fractions of inches and line length in multiple feet, so wall friction tends to dominate. Assuming everything is sized correctly, you cannot be too big with a remote pump/regulator set up.
Why is ethanol added to fuel?
Since ethanol is used to oxygenate the gasoline mixture, which in turn allows the fuel to burn more completely and therefore produce cleaner emissions, its use in fuel has obvious benefits for air quality.
How are fuel line fittings measured?
How to Measure a Fuel Line DiameterUncover the fuel line so that it is visible and can be reached easily. Do not remove the fuel line or disconnect it.Place the top of a 1/4-inch wrench with an open end over the fuel line. Slide it carefully over the line so that it fits snugly against the tubing.
What size fuel lines do I need?
Most stock applications came with 5/16-inch fuel line, but for many street vehicles and mild race applications 3/8-inch (AN 6) fuel line is a good upgrade. High performance applications and racers using alcohol will use 1/2-inch (AN 8) fuel line.
