Where is the fuel pump located on a 1997 3500 Chevrolet 6.5 liter turbo diesel?

There are Two! the first one is on the frame rail, drivers side, it looks like an inline fuel filter with two wires coming from it, that is the syphon pump, it is about $90. The second one is the fuel injection pump it is on the top of the motor under the intake it looks like a large squid withe the 8 fuel lines coming from the back of it, it is about $1200. hope this helps!
