GSR fuel pump

[Medabots]

Hey guyz, whats up?
I just have one question, I swap a 95 LS engine in my 94 hatch but I never changed the fuel pump. My friend gave me his GSR fuel pump and I instaled in my car. I took it for a ride wiht the new pump but i did not feel a diference.

does the GSR fuel pump make a difference in performance or is just like the stock 94 civic DX on a LS engine?

First I don't think there is any difference in flow rates between the 2 pumps, but even if there is fuel upgrades don't make power. You can upgrade you fuel system all you want, but if you aren't pushing more air in there it will do you no good.

your 94 hatch fuel pump is fine.

actually there is a difference between an LS fuel pump and a GSR fuel pump. the LS pump flows 222 fl oz a min and the GSR flows 360ish fl oz a min according to the helms shop manuals. however there is no difference between any civic fuel pump and the LS pump so there is no reason to upgrade unless you are going FI and even then you might not need it.
