The car died on me a week ago due to a failed fuel pump. I have since ordered one, and put it in, however, I still can't keep the car running.

It will sometimes start but then die a 1-10 seconds later. I'm sure I am not getting enough fuel pressure.

I just replaced the fuel pump motor, and did not opt for an all new fuel pump assembly.

Is there a trick to putting the pump in the assembly to restore full fuel pressure? I have the bottom pump screen/nipple inserted into the the rubber grommet on the bottom of the assembly housing, and the outlet nipple from the top of the fuel pump motor going into the outlet tube on the top of the assembly. For some reason, I can't get it to push out at a decent enough pressure to run the car appropriately.
