What Size Is The Fuel Line On 66 Mustang?
Most classic Mustangs prior to 1969 have 5/16-inch fuel lines designed for six-cylinder engines or small-block V-8s. However, when horsepower rises above 300, your Mustang needs a 3/8-inch line from fuel tank to carburetor.
What is the standard size for fuel line?
Typically, these 1/4″ and 5/16″ line sizes are in use for low flow or OEM systems, but are commonly used in high performance applications for pressure gauges as well as plumbing between the Regulator and Intake Manifold.
How much HP can a 3/8 fuel line handle?
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.
What size fuel line do I need for 1000 HP?
For instance, an 8AN feed line and 6AN return line on a 1000 horsepower gasoline or race gas powered LS with 30psi is sufficient.
What size should my fuel return line be?
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.
What is the outside diameter of 3/8 inch fuel line?
JEGS Aluminum Fuel Line | 3/8 Outside Diameter | 0.035” Wall | 25 Feet | 25 PSI Maximum Pressure | Seamless.
Can I use rubber hose for fuel lines?
Standard rubber vacuum or heater hose should never be used in fuel applications. The hose will deteriorate from the inside out and can plug fuel filters and carburetors with rubber debris, long before it springs an external leak.
What happens if your fuel line is too big?
If the diameter is too big: the lines will take longer to pressurize. If your pump can’t maintain the pressure, it can drop during times of high demand, leading to engine damage. It is an unnecessary expense, bigger is more expensive.
Does fuel hose size 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.
How big is the fuel line on a Top Fuel dragster?
… The fuel-line pressure for NHRA Top Fuel dragsters and Funny Cars is between 400 and 500 pounds, about 20 times greater than the pressure on passenger-car fuel pumps!
Are braided fuel lines worth it?
Braided hose provides better heat dissipation and better flow, which is important when choosing performance car parts. Additionally, braided lines are able to withstand more pressure than rubber lines.
Can PVC tubing be used for fuel line?
Can PVC and other plastic hoses be used for fuels and gas? In short, the answer is no, they cannot.
What is the best material for fuel lines?
Metal Lines
They are usually made from stainless, aluminum or coated steel tube. Metal is the best material for fuel lines.
What is the OD of 3/8 rubber fuel line?
FUEL LINE HOSE 9.5MM (3/8″) NITRILE TUBE ID 10MM X OD 16MM NON-FUEL INJECTION 50 PSI – Collier & Miller.
What is the outside diameter of 5/16 fuel line?
Inside Diameter: 5/16″ (7.41mm) Outside Diameter: 7/16″ (7.83mm)
Which fuel line is the return line?
The vapor-return line normally runs from the fuel pump or the fuel filter to the fuel tank. This vapor-return line is connected to a special outlet in the fuel pump. Any vapor that forms in the fuel pump returns to the fuel tank through this line.
What is the outside diameter of a 3/16 fuel line?
O.D. x 3/32 in. I.D.
What size an line is 3 8?
THE 3 BASIC ELEMENTS OF PLUMBING
| Standard Automotive Hose Size | -AN Equivelent Hose Size | |
|---|---|---|
| 3/8″ | = | -6 AN |
| 1/2″ | = | -8 AN |
| 5/8″ | = | -10 AN |
| 3/4″ | = | -12 AN |
What size is 8 an fuel line?
Let’s look at AN8 Hose For example, remember from before AN8 equals 1/2 inch. However this does not equate to 1/2 I.D. of the hose. This AN8 performance hose would be equivalent to a 1/2″ Hard Line measured on the O.D. of the hard line tubing.
What do you seal fuel line threads with?
Permatex Thread Sealant with PTFE (Polytetrafluoroethylene) is an economical general-purpose fitting sealant that seals and resists pressure in air, oil, diesel fuel and hydraulic systems, outperforming tapes and pipe dopes.
Do you put anything on a fuel line threads?
Sealing Fuel Fitting Threads
For most components such as a pre-fuel filter (aka fuel water separator) the thread type is typically NPT or NPTF and requires sealant around the threads.
