For a car/truck (ie: not a bike) what is the location preferred for the Fuel Shut-off? I am running electric pumps, with an inertia switch. I will list my two conflicting thoughts below.
Fuel Shut-Off between tank and Pump: Pros: Shutting off fuel close to tank means any fuel line rupture won't drain the tank into the fire.
Cons: Fuel Line from shut-off all the way to the engine is still full of fuel, in the case of an engine fire, this will only feed the fire.
Fuel Shut-Off at engine:Pros: During Engine Fire, fuel is shut off closest to the fire, reducing the volume of fuel available to the fire due to fuel line integrity failure.
Cons: Roll over or other crash could rupture lines and drain tank.
I work on Helicopters and the fuel shut-offs are ALWAYS close to the fuel cell outlet. But Jet Fuel (glorified diesel) has different characteristics than gas.
If I put the shut-off at the tank, then run hard line to the engine compartment, will tech want a fire sleeve on the braided part going from the frame to the engine, a fire sleeve on everything, or nothing at all?
I did a search and came up with more questions than answers. Thanks in advance.
