Hello everyone!

1991 Honda Civic Base 1.5L DPFI SOHC
So I have the classic "car dies when coming to a stop when below half a tank" problem, with a few new developments that I would like to see if anyone has any input on.

I searched this issue an found a few informative threads, but I don't match the described symptoms exactly.

When my tank is around half full, I start having an issue with the car starting to stall when I am braking and slowing down, but unlike the others, I can always prevent it from stalling by giving the car a little gas at the same time (two foot action ). I know that the car has an aftermarket fuel pump installed by the PO. So I just ordered the new Airtek fuel sock described in the other thread, but I am not positive that is the root of the issue. Why would keeping the car rev'd up prevent it from stalling? I would think that if the pump was sucking air, revving would make it worse (depleting the fuel and pressure behind the injectors). The car also will start right up if I fail to save it. Now I suppose I could be right at the borderline of this issue, as I usually fill up right after I notice this issue, and that if I wait until the tank is even lower, then potentially I would not be able to save it from stalling, but I am not sure.

Any advice would be appreciated!

I figure I will also add that from talking to the PO (my buddy) the fuel pump was installed by his drunk grandfather . So is it possible that the pump could be installed in some other orientation that could cause these issues?
