Sportrak fuel pump

Forum: 

Hi just fitted a new fuel pump to my sporty fuel injection model, the pump makes a noise as if it is working when the ignition is switched on. As the engine didn't start I loosened the banjo on top of the filter and tried again, no fuel in evidence at the banjo, The pump is not like the original being slightly larger and having two terminals for the wiring, I have read elsewhere on this forum of a member getting a pump from the same place Jap parts, apparantly with no problem. I am wondering if I have a dud pump or am I missing something Unknw
