What size fuel line do I have?
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. Thanx....looks like mine is 3/8. I couldn't even get a 5/16 wrench to fit it. Tubing is OD (outside diameter) and Pipe is ID (inside diameter).
What size is a 30r6 fuel line?
SAE ratings displayed on the hose should be 30R6 or 30R7.

Is 6an the same as 3 8? No they aren't exactly the same.
What size fuel line for 350 2bbl?
A 350 2bbl car will probably have a 5/16" fuel line. To measure for sure, take an open end wrench and try to slide the open end over the tube. This will be very close. 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.

Can fuel line be too big?
Registered. Actually you can have too big a fuel line...if the line is too big and your car accelerates hard yet you don't have a massive fuel pump, you will have the additional weight of the fuel in the line pushing back and fighting the fuel pump which can cause cavitation.Jan 26, 2016

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 gauge. If the pressure falls as the engine RPM's go up you need more pump head.Nov 16, 2012

What is fuel hose?
A fuel hose（ https://en.wikipedia.org/wiki/Fuel_line ） is a hose used to bring fuel from one point in a vehicle to another or from a storage tank to a vehicle. It includes Fuel injection hose, Marine fuel hose, Farm fuel hose, Diesel fuel hose, Fuel transfer hose.
How much fuel pressure should I use for fuel injectors?
Most injectors are rated at 43.5 psi (which is about 3 bar ). By changing the pressure, you change the flow rate. If you need 25 lbs/hr, and there is an injector that will flow 24 lbs/hr at 85% duty cycle, it is possible to use more fuel pressure to make the injectors flow more. It is better to do this when the injectors are just a little too small, than to go to larger injectors. The chart below will show what can be done by adjusting fuel pressure. You can see from the chart that there are quite a few options to get very close to what you'll need.
How much duty cycle does an 8 cylinder injector need?
Now if it is an 8 cylinder engine you can figure out that each injector must supply 22.5 lbs/hr. Injectors will work best if they don't exceed more than 85 duty cycle. An injector that flows 26.5 lbs/hr will be at an 85% duty cycle when flowing 22.5 lbs/hr, but you may not find an injector that flows exactly what you need. It is best to step up to the next size, for our example, we might need to step up to 30 lb/hr injectors. The formula for injector sizing is:
How much fuel do you need to make 400 horsepower?
In order to know what size injectors you need, you'll need to know how much fuel it takes to make the desired horsepower you want. The BSFC is simply how many pounds of fuel it takes to make 1 hp for 1 hour. BSFC will be about 0.45 for most street injection set ups. This means that if you have a 400 hp engine with a BSFC of 0.45 you'll need 180 lbs of fuel per hour to maintain 400 hp. The formula for pounds of fuel per hour is:
How much gasoline is needed to make 1 hp?
These figures are for gasoline engines and figured assuming a .05 BSFC ( . 5 lbs. of gasoline is needed make 1 hp for 1 hour). If you're in doubt, it's better to have more fuel flow then too little.

Notice how close all the VP racing fuels are, this makes VP an excellent choice for a high rpm, high compression racing engine.
What size is motorcycle fuel line?
The correct fuel line is metric sized 5.3 or 5.5 mm, which fits on the nipples properly.
Where is the fuel line on a dirt bike?
The dirt bike fuel filter is attached to the fuel line and located in the middle between each end. You’ll want to clamp either side of the filter to cut off the fuel. The filter is attached to the fuel line using similar clamps noted above.
Can a fuel line be too big?
The fuel line size being too large won’t really affect the fuel pressure. Excessive fuel pressure is what can cause the fuel to overrun the needle/seats and flood the motor with excess fuel. That being said running a -8AN fuel line is beyond overkill for a 340 but it shouldn’t adversely affect it.
Can tygon tubing be used for gasoline?
Specifically designed to handle most fuels and industrial lubricants, it is routinely used with gasoline, kerosene, heating oils, cutting compounds, and glycol-based coolants.
What is an an fuel line fitting?

Does a fuel return line have pressure?
A free flowing return line maintains consistent pressure in the system. Ending the return above the fuel level in the tank, or in the filler neck will cause aeration. This can lead to fuel starvation and pump wear.
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?

What is the difference between a 5/16 and 3/8 fuel line?
We get it. But there is a little more to it than that. 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.
How to know what fuel line is on a combustion engine?
The basic functionality of a combustion engine and the fuel demand for the horsepower is the same! You will also know what fuel line is supposed to be there by looking at the hook up on the engine. Wherever you hook up the fuel line on the engine there will be a hose barb. If it is a 5/16″ or a 3/8″ hose barb, that is what you should use.
What is the A2 hose used for?
A2 Hoses: Are used for the fuel tank vent hose below the deck. They aren’t designed to have fuel sitting in the hose but do have a fire-resistant covering on the outside of the hose. B1 Hoses: Are used for feeding fuel from the boat fuel tank to the fuel filter bracket BUT ABOVE THE DECK OR NOT ENCLOSED!
What is the difference between a B2 and A1 hose?
They are basically the same as the A1 hoses but do not have the fire-resistant covering that is on the outside of the hose. B2 Hoses: Are used for the fuel tank vent hose BUT ABOVE THE DECK OR NOT ENCLOSED! Basically the same as the A2 hose but without the fire-resistant covering on the outside of the hose.
Why is my fuel pump running lean?
If the fuel pump is sucking in air every time it tries to get fuel, it will aerate the fuel and run the engine lean. Giving you all kinds of different problems!
What fuel line do you need for a Honda engine?
The general rule of thumb still stands regardless of what manufacturer engine you have! Whether it be Honda, Mercury, Yamaha, Suzuki, Tohatsu, Nissan, or Johnson/Evinrude. Any engine that is above the 115 HP requires you to use a 3/8″ fuel line! The basic functionality of a combustion engine and the fuel demand for the horsepower is the same!
Why is it important to have a fuel line installed?
Going back to the straw theory, having the correct fuel line installed will help ensure the proper fuel consumption for the engine. Thus, keeping up and even prolonging the life of the engine. You don’t want to cause premature failure of the engine or any of the components that are in the fuel system.
