The almighty fuel pump

Ok guys well I know that after a few minor mods to these cars that the fuel pump starts to decide to be weak. I have never really seen a thread on putting better ones in.

What do you guys usually upgrade to when you get a new one for your small modded TBI? I just dont want to go into overkill you know.

You will be fine with any walbro or stock GM TPI pump. Walbro pumps are cheaper and can be had for $97 to your door. Try a few searches for "fuel pump" or "Walbro fuel pump".
