It's interesting to see that not even the manufacturers have an agreement on the placement of the Fuel Shutoff valve.

When looking at a Jetcentral manual, the installation drawing for a turbine with kerostart says that the valve goes before the fuel pump. For the same turbine but this time with gas start, the installation drawing shows the valve between the pump and the solenoid.

When looking at a Jetcat manual, the installation drawing shows the valve installed after the solenoid. In some other drawings (kerostart), they don't even show a shutoff valve in the drawing.

In the Wren manuals, no mention of a shutoff valve.
