What is the correct fuel pressure from the fuel tank?
Depends on the year, make and engine. Need more info.
fuel pressure regulator is in the tank, in the pump assembly 1995 it is NOT in the fuel tank. Later models it is ON the fuel tank, but this model has it on the fuel rail. I believe under the intake manifold. It is on the pump, in the tank. There is no regulator under the intake. Some fuel rails have a pressure damper on them, that looks like a regulator.
Most military flamethrowers have a pressure tank, holding compressed gas to push the fuel out of the weapon, and a fuel tank, holding liquid fuel. There is no air inside the tank. If a shot penetrated the fuel tank while it was under pressure, it would spray fuel (that may ignite), but would not be likely to explode.
It is attached to the top of the fuel pump module. It can be replaced without removing the fuel pump module from the tank. There are two electrical connectors attached to the top of the fuel pump module. One has 4 wires that operates the fuel pump and fuel gauge. The other has three wires that operates the EVAP system pressure sensor.
