keeping the oem sensors working can be frustrating. Besides trying to keep them working, replacement Options include
1) horst miracle probes. they at least have a teflon insulator and a shroud on the black tank tip to keep TP etc off of it. just pull the factory sensors out, push in the miracle probes. They aren't foolproof but do work better than the junk oem probes. My experience, they are great on grey/fresh tanks, but can end up still being erratic on black tank.
2) sealevel or similar external sensor system: being external they are almost immune to bad readings. get enough buildup and they can be problematic, but pretty rare. Give a better reading of actual level, mine read in 5% increments but the systems aren't inexpensive. Sealevel works with std wiring, the other system I know of does not. Sealevel can't be calibrated to take into account non rectangular tank (e.g. black/grey) the other system can.
