What size rubber fuel line do I need?
For Fuel Lines If your engine releases 350 hp or less, use a 5/16 inch-sized fuel line hose. Less than 450hp engine emission needs a 3/8 inch-sized fuel line. 450 to 650 hp engine would need1/2 inch fuel line. Use 5/8 inch for more than 650 hp engines.
How does the size of the fuel line affect the pump?
The larger the line, the lower the pressure drop at a given flow rate, and the longer the line, the higher the pressure drop at any flow rate. The pump has to suck fuel up the line and once your positive suction head drops sufficiently, you start boiling the fluid in the line and you ‘max out’ your line capacity.
How big of a hose do you need for a fire pump?
Hose stream demand is the amount of water that must be added to the sprinkler system hydraulic calculation to fill the hoses as well as ensure enough supply to operate the sprinklers. Inside hoses are generally 1- to 1½-inch standpipe hoses that may be connected to the sprinkler system for initial fire attack.
How big is a ½ inch fuel line?
The ½” line will result in a ½ pound drop versus the 3 pound drop for the 3/8” line at the stated flow of 83.3 gph (enough to support 1000 HP at a BSFC of .5). The pressure drop at 1320 HP thru a 3/8” steel line might be around 5 psi.
How does a fuel pump work in a muscle car?
The pump has to suck fuel up the line and once your positive suction head drops sufficiently, you start boiling the fluid in the line and you ‘max out’ your line capacity. This is even more an issue with impeller (electric) type pumps, but it’s true of mechanical ones too. So first, how much flow do you need for 450HP?
How big of a hose do you need for a pump?
Likewise, things such shorter hoses and lack of elbow adapters will help reduce the effects of undersized hoses. Maximum recommended velocities are as follows. Suction lines (hose between the reservoir and pump) should not exceed 4 feet per second.
The ½” line will result in a ½ pound drop versus the 3 pound drop for the 3/8” line at the stated flow of 83.3 gph (enough to support 1000 HP at a BSFC of .5). The pressure drop at 1320 HP thru a 3/8” steel line might be around 5 psi.
How big is a hose compared to a GPM?
Hose size VS Gpm Hose Size in inches Hose Size in inches Hose Size in inches Hose Size in inches Gallons Per Minute (GPM) 0.25 0.38 0.50 3.50 0.25 1.63 0.73 0.41 0.01 0.50 3.27 1.45 0.82 0.02 0.75 4.90 2.18 1.23 0.03
What happens if you use an undersized pump hose?
Using undersized hoses can result in pump cavitation, back pressure, excessive heat, and component failure. Keep in mind this chart shows recommended velocities, there are other factors that may affect your system.
