What makes a good marine fuel line?
Marine fuel lines should meet certain USCG regulations that take into account the permeability of hoses and some other criteria. The point is, most of these parts can pass the vapors of hydrocarbons.

Is marine fuel line the same as automotive fuel line?
Marine-grade fuel hose is much heavier than the same inside-diameter hose as used in automotive applications. This is done as part of its fire or flame testing, a requirement under the regulations. All fuel hose used in engine room spaces on board gasoline-fueled boats must meet a 2.5-minute fire test rating.
What is the best fuel line for diesel?
The American Boat & Yacht Council (ABYC) recommends the Type B1 fuel hose for diesel-based applications. The Type A1 hose is the best option for gasoline supply. This hose is less permeable, highly durable, heat resistant and does not collapse under high pressure or vacuum.
What is marine grade fuel hose?
These are specifically designed and branded for use in supplying fuel to motors in boats or marine vessels. USCG Type A1 hoses are designed for fuel feed applications where the fuel is constantly in the hose, whereas Type A2 hoses are designed for fuel fill type hoses only.
What size is marine fuel line?

Does diesel need special fuel line?
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 vinyl tubing OK for diesel fuel?
Use only fuel rated hose for everything between the tank and the IP. Tygon hose is fine for return lines, and you could even get away with vinyl hose for the returns just temporarily for testing purposes.
What is USCG approved fuel line?
MPI Fuel Hose USCG Type A This premium quality fire-retardant fuel hose meets or exceeds all requirements of new ISO 7840 and SAE J5127 standards required by USCG, ABYC and NMMA. Inner tube material provides extraordinary resistance to gasoline, diesel and alcohol-enhanced fuels.
What is the difference between A1 and A2 fuel hose?
Hose used for diesel supply and return applications must carry an A1 rating, while fill and vent installations call for hose designated as A2 (A1 is acceptable for fill and vent hose, however, A2 hose should not be used for anything other than fill or vent applications as it's not designed to be continuously filled ...
How long does marine fuel line last?
The EPA defines useful life as 10 years for boat fuel system components and five years for PWC fuel systems.
Which is bigger 5/16 fuel line or 3 8?
The 5/16″ fuel line is actually perfect for smaller outboards. Being a little smaller than the 3/8″ hose, it works great for little kicker motors, and sailboat outboard engines.
What size fuel hose do I need?

How much horsepower can 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.
What is the best fuel line material?
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.
What is the best metal for fuel line?
Most cars come from the factory with Metal Lines because they hold up better than any soft material. They are usually made from stainless, aluminum or coated steel tube. Metal is the best material for fuel lines. However, it can be difficult to fabricate.
Is vinyl tubing good for fuel line?
No - unless specially made for this purpose do not use plain ordinary vinyl tubing for gasoline and other hydrocarbons.
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 algae in diesel fuel?
Algae is basically a plant that needs photosynthesis to exist and proliferate. That means you would need sunlight in your diesel fuel tank to create algae. Trust me, if you have sunlight getting into your diesel fuel tank, you have bigger problems than plant growth inside the tank. Other microorganisms can exist quite happily in the dark however, ...
How does ethanol affect boating?
There’s been a lot written in recent years about the effects of ethanol-laced gasoline in the boating world, and all of the issues—both real and perceived—related to how it may impact fuel systems and the performance and reliability of marine engines using it. Not nearly as much much has been said about diesel fuel, which on a quieter level has undergone changes as well. First, the EPA has required significant reductions in the amount of sulfur in diesel fuel. We’ve learned over time that the amount of sulfur in the fuel is directly linked to the amount of pollution produced when the fuel is burned in an engine. Diesel engine exhausts emit soot and particulates, and oxides of nitrogen (NOx) which contribute to smog and acid rain. Additionally, there are some hydrocarbons, some carbon monoxide, and other small traces of hazardous air pollutants.
Why is a fuel filter important?
Because of the enhanced probability of water ending up in your diesel fuel, a top quality water-separating fuel filter is extremely important for any diesel engine. Filtering particulate matter is important too. However, it’s also important not to overdo it here.
How much more efficient is a diesel engine than a gasoline engine?
And diesels are about 30 to 35% more efficient than their gasoline-fueled counterparts. Just remember that with today’s newer diesel engines, it’s imperative to follow the manufacturer’s recommendations to the letter when it comes to things like fuel additives, engine oil, and cooling system contents.
What is waxing diesel?
Another property exclusive to diesel fuel is a phenomenon known as “waxing.”. In the US there are essentially two types of diesel fuel available, No.1, which is essentially kerosene, and No. 2, used for home heating and diesel engines.
What is the effect of diesel exhaust?
Diesel engine exhausts emit soot and particulates, and oxides of nitrogen (NOx) which contribute to smog and acid rain. Additionally, there are some hydrocarbons, some carbon monoxide, and other small traces of hazardous air pollutants. Modern marine diesels like this turbocharged Yanmar have a safety edge over their gasoline counterparts ...
How long is diesel in storage?
Diesel is in fact often in storage for months before it reaches its final destination, your engine. Additionally, it may get moved from one storage tank to another, and pick up water and other contamination along the way. Temperature change also impacts the fuel; it will tend to thicken in cold weather without additives.
What side of the system is diesel fuel circulated in?
Diesel fuel not used for combustion is circulated in the low-pressure side of the system for lubrication and cooling. By Ed Sherman. March 16, 2013.
What side is the red arrow on fuel injector?
The softer fuel-return lines shown by the red arrow are on the low-pressure side of the fuel circulation system. Answer: You have a good eye! Not to worry though. You are right that on your engine the fuel injector pressures are quite high.
What side of the system is the rubber hose on?
The rubber hoses you refer to are on the low-pressure, return side of the system. Diesel injection systems are closed, full loop systems.
Does diesel fuel go to each cylinder?
In other words, fuel gets sent to each cylinder, but the system always sends more fuel than will actually be used as the engine runs. Diesel fuel serves multiple functions when the engine is running, more than just providing a flammable fuel for combustion.
