If your using the stock in tank fuel pump, it is already on a Relay
under the hood. The pump will have power when the key is on, and no power
when the key is in the off or lock positions.
If your going Drag Racing, and the NHRA requires a inside shut off
switch, you just need to find the key on wire from the relay and put a fused
switch on that.
The stock intank pump will flow around 60 PSI of fuel pressure. If your
going Carb, use a after market fuel pressure regulator. The car is already
plumbed with a return line to the tank.
Im not sure on an 87 V6 car where the fuel pump relay is under the hood,
or which wire is the key on power wire.
all the fuel pump wiring and all other wiring going to the computer has
been removed from under the hood. that incules the fuel pump relay and
fuse. what i have done is hook the electronic fuel pump to a switch,
then to another switch that i hid so that my car can not b stolen if
some one as to try they would not find how to turn on the fuel pump,
making it harder to steal.
i wired it with a inline fuse and then the switches to the power when
the key is on. with the electronic fuel pump i hooked up a fuel pressure
regulator with the return line. i think this set up will work better
then even the mechanical fuel pump. thanks for all your help.
