How much pressure is in a fuel system?
How much pressure is in a fuel system?
Required fuel pressure can vary depending on your vehicle’s engine and fuel system. Carbureted engines may require as little as 28 kPa (4 PSI), while modern multipoint fuel injected high- performance engines can require as much as 414 kPa (60 PSI).
What should fuel pressure be on sniper EFI?
Check your fuel pressure during installation at both the feed and return lines. Feed pressure should be knocking on 58 PSI and the return should ideally be zero, if the feed pressure is not correct, or if the return line pressure is greater than 4-5 PSI find and correct the restriction before proceeding.
Where does the high pressure fuel come from?
The high pressure fuel is provided by a series of 3 fuel pumps, a pulse operated lift pump and 2 electric pumps inside the VST or vapor separating tank. From there the fuel flows to the fuel rail where it is cooled by sea water and delivered to the fuel injectors.
Where does the fuel pump come from on a sniper?
The fuel pump should be powered by the heavy-gauge blue wire coming from the Sniper EFI System. There should be no relay added to this wire. Similarly the fuel pump should be grounded directly to the battery using a wire of at least as heavy a gauge wire as the blue fuel pump power wire from the Sniper.

How does the fuel injection system work on a Harley Davidson?
Ion Sensing System – This system uses ion-sensing technology to detect detonation or engine misfire in either the front or rear cylinder by monitoring the electrical energy at the spark plug after every timed spark.
What should the fuel pressure be on an Edelbrock sump engine?
These units are ideal for use with various aftermarket EFI systems and with many popular engine swap applications that require constant 35-90 psi fuel pressure. The systems feature a new compact design that’s adjustable from 35 to 90 psi and include a vacuum reference port.
Where is the fuel pump regulator on a Harley Davidson?
Fuel Pressure Regulator – Alsolocated in the fuel tank, the regulator controls fuel pressure between 55 and 62 PSI by returning excess fuel from the fuel pump back to the fuel tank. The return is also located in the tank, hence only one line (supply) coming out of the tank.
