 go back to NAPA and ask for a relay with part number AR204. This is a 
standard Mini ISO relay. Connect 12V from battery to post 30 (you could 
run this through your inertia switch that I think I remember you talking 
about). Connect the fuel pump to post 87 (switched normally open). 
connect a 12 volt source (controlled with the ignition switch) to post 
86 and post 85 to your other switches (oil pressure I think). Post 87 
will not be used (should shield it since it will be hot).

I can send you a simple schematic of this relay if you need it.
