i got a 2000 s 281s/c with the saleen boost and fuel pressure guage in the pod on the dash. the fuel pressure guage was never hooked up, and i need to know what sending unit i need to get the thing working. i caqn see the wire tie wrapped to the ac line under the hood, but doesnt go anywhere. any help on this would be great, i hate to watch the boost guage and see the other not doing anything..thanks Jon
