Re: 90 Civic Si stalling problem
 

Okay so I dropped the tank and pulled the fuel pump out. The joint
connector was missing along with the sock filter. I went to autozone
got a new sock filter. The design had changed instead of having a
joint connector to the sock filter the sock filter just connects to the
bottom of the fuel pump and the gasket goes overtop of it for a snug
firm fit.

So In the end:
Problem: Fault joint connector that connects to the sock filter on the
bottom of the fuel pump

Solution: New sock filter without the joint connector.

This had to be the weirdest solution as I have asked many mechanics
about my problem and none had this as a solution so I guess I was
pretty lucky. Now my 90' Civic Si is running sweet. Thanks for all
the help everyone.
