NTFDAY & RSPEARS I don't think that's the problem for the following reasons: Runs great every so often. I coated the interior of the tank a few years back and recently opened up the top and it looks clean inside. The filter between the tank and the fuel pump remains clean. I used to have a submersible pump and modified the top of my tank to accommodate the pump and fuel level sending unit so I have great visibility into the tank. Another fellow recommended I change out the CTS and I'm going to try that - right before I pull my hair out.
