WebDec 6, 2009 · The common 12v carter 6psi-8psi electric P4070 P4594 pumps will support 450+hp thru 3/8" fuel line. One pump is not enough for a 500 horepower motor, but two are plenty. If your engine makes 500+hp you need two of them in parallel. If you find your Carter pump (or any other electric fuel pump) to be noisey you need to look at how it is mounted. WebPerformance curve charts are provided for every individual pump to show the working range of the pump. These charts show a graph of how many gallons per minute (GPM) and/or liters per minute (LPM) liquid will flow at …
WebAeromotive, adjustable bypass regulators are available to use with non pressure limited pumps that can handle flow from small to large pumps, and that can create and maintain pressure from carbureted to EFI levels. Most EFI regulators are adjustable from as low as 30 PSI to as high as 70 PSI, so those who want 43 PSI for the fuel rail will be ... WebAn electric fuel pump uses electrical power and typically uses a motor to rotate a piston or diaphragm that transfers the fuel. The electric fuel pumps are installed in the fuel tanks. This pump generates high pressure in the fuel pipes …
WebNov 21, 2024 · When the pipe between the test header and the pump discharge flange exceeds 15 linear feet, the pipe diameter must be increased to the next size up. When transitional fittings are required to reduce or increase the pipe diameter at the pump flange, care should be taken to select the proper reducing fitting. WebSep 17, 2014 · Fuel pumps are generally found in two major areas: on the frame rail or inside the gas tank. Newer vehicles usually have them inside the tank for a couple of different reasons. The major reason is that it allows the gas tank to run closer to empty without damaging the fuel pump; in case of a pump failure, the gas leak is contained in the tank.
WebGM requires 70-72psi to feed the high pressure mechanical pump on LT1, LT4, and LT5. However, this high pressure is only needed under high fuel/high engine speeds. The need for the higher pressure is so that the mechanical pump cavity can completely fill. During idle and cruise, where the opening time of the mechanical pump is longer, a lower ...
WebPump sizing involves matching the flow and pressure rating of a pump with the flowrate and pressure required for the process.
