So, as the title says... I have (and have been running for years) the "new" DMCH combo unit in my tank. Pump has had its share of issues (on the 2nd or 3rd one now I believe?) but yesterday it pulled a new trick on me. For no reason, after a nice long drive with no issues, the gauge went to 0 and the fuel light came on. I know I had 3/4 of a tank. Opened the tank (removed the stainless plug where the old sender goes) and verified that the tank was indeed full. Checked the electrical connections at the combo box logic unit, which I know is futile since the light was on so there's clearly power there - solid. Went to a gas station and topped up that 1/4 tank to see if maybe it would shake something loose - no dice. Pump is running A-OK, no issues there.
I haven't yet removed the pump body from the tank, as with a full tank of gas that is going to be a messy proposition. Anything else I can or should try in the meantime? I tried to see if I could discern the position of the float through the sender plug hole, thinking maybe it got pushed to the bottom somehow, but I can't seem to see it.
What gives?
This unit has sort of been more trouble than it's worth - for what it cost I could have had two replacement Bosch pumps and $250 worth of liquor... an appealing prospect given the amount of times I've had to R&R this thing.
