My car needed a new gas tank because the fuel line was damaged. I found one used without the fuel pump, but my old one had been working fine so I installed that. I saw trace elements of water in the basket the pump sits in and removed it, but used all the other parts, including the sending unit. It has run terribly since. Stopped the tank again to put in the old sending unit and that seemed to fix the gauge problem. So, the tank had the old pump and sending unit. The only thing existing are some little screen looking things that I'm not familiar with. Could they be the problem? I have even changed out the plugs, wires and distributor cap in case it was a spark issue for some reason. It ran alot better (not normal) but is back to the same running condition. Really rough idle and no power.
