Injection Pump Fuel Flow Question

[Dan Stokes]

I've been trying to find a way to simplify my fuel shut-off system on the S-10. As I looked at the fuel supply system it caused me to wonder:

1) If I put a solenoid valve right after the pre-filter (which in my case is about 5" from the underhood fuel tank) would that cause an engine shut down?

OR......

2) Would the fuel filter cycle it's contents until empty, delaying the shut down until the filter is drained?

3) If I did something along that line would I just NOT put vacuum to the IP shut-off system?

Input!! I need INPUT!!!!

And thanks -
