I've been having problems with my car horribly Hesitating below 3500 RPM's. After some research I decided to try removing the Fuel Pump and cleaning it.

I just got done doing this and it didn't seem to help. I did notice that the L-Shaped Sock was slightly clogged with stuff but not overly clogged. I cleaned it with Carb cleaner and reinstalled it. Took it for a test drive and it still was hesitating like before.

I am close to buying a new Fuel Pump because I have persued everything electronic it could be (Plugs, WIres..etc) I am going to buy a fuel filter and probably a Fuel Pressure Regulator and if that doesn't work then I will probably go with a new Pump.

Anyone have any other thoughts....From what I have seen the returnless fuel pumps are the ones everyone's been having problems with....Should I just go for the whole unit or should I try replacing just the Stock?

I saw just the L-SHaped Strainer Sock listed on Autozone's website....but from what I have read here no one has replaced just the sock. Or have you?

Any help would be great!
