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.
How much pressure can 3/8 fuel line?
Working Pressure: 300psi.
What size fuel line do I need for 1000 HP?
Recommended Size, Based on Horsepower
| Recommended Fuel Line Size (from the tank to the pump) | ||
|---|---|---|
| Engine Output | Size (inches) | Size (AN) |
| 350-450 hp | 3/8 in. | -6 |
| 450-650 hp | 1/2 in. | -8 |
| 650-1,000 hp | 5/8 in. | -10 |
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.
How much HP can a mechanical fuel pump support?
750-900 hp
The HP mechanical pump can support 750-900 hp.
How much horsepower can 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.
Does fuel line size affect pressure?
Every fuel line experiences pressure loss depending on fuel line length, and fuel flow rate.
What size fuel pump do I need for 600hp?
50 gph
Making the Choice
| Fuel Pump Free Flow | Carbureted Engine | Carbureted w/ Power Adder |
|---|---|---|
| 50 gph/190 lph | 600 hp | 500 hp |
| 67 gph/255 lph | 750 hp | 650 hp |
| 90 gph/340 lph | 1000 hp | 850 hp |
| 125 gph/470 lph | 1300 hp | 1000 hp |
Is braided fuel line better?
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.
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!
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 much pressure can a fuel line take?
While most fuel systems can be upgraded to handle upwards of 700 kPa (about 100 PSI), it should also be understood that too high fuel system pressure can easily lead to distortion or damage.
How much pressure does a fuel line hold?
Working pressure is not relevant, but wire-inserted hose can withstand 50-85 psi, depending on diameter. High-pressure fuel hose for clamp-type fuel-injection systems is also available. This fuel hose is SAE 30R9-rated and uses a fluoro elastomer inner liner that will withstand up to 180 psi and 300 degrees.
What fuel pump do I need for 500hp?
Horsepower
For example if your pump flows at 50 gph it should be able to support a 500 hp engine (50 x 10 = 500). However, to actually know the gph you must also consider the fuel pressure required for your engine.
Does adding a bigger fuel pump increase horsepower?
By itself, a high-flow fuel pump will not increase power, but it will provide the ability to increase power by providing a higher flow of fuel to the engine when major engine upgrades are performed.
Are metal fuel lines better?
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.
What size is 6an fuel line?
[Size] ID of 6an fuel hose:0.34″(8.63mm),OD:0.54″(13.71mm).
What size fuel line do I need for LS swap?
AN LS stock fuel rail setup utilizes 3/8 inch quick connects on the feed and 5/16 quick connects on the return, both available from Hot Rod fuel hose LS swap kits. You will still need a filter before the fuel rails and you will want to ensure the correct fittings and pump are used for your install.
Will increasing pipe size increase gas pressure?
Pipe length
The longer the pipe, the lower the gas pressure. But, you must also take into account the pipe’s nominal size. Pipe with smaller nominal size may restrict the pressure flow. Large pipe delivers higher pressure, but it comes with concerns about cost-effectiveness.
Will increasing fuel pressure increase power?
Changing the fuel pressure on an EFI System is an effective method of affecting engine performance and making more power.
Does increasing fuel pressure increase flow?
However, increasing the fuel pressure causes more fuel to flow through the original injectors, meaning that it’s a cheap and effective approach to take.
