The level sender merely screws to the side of the FDM & its wire plugs onto the tank plate. Before reinstalling the FDM, I removed the EEC PWR relay (which also kills the FP relay), turned the key to RUN, & checked both the old & new senders through the full range of motion. The old was definitely bad, & the new definitely good.

To temporarily or permanently convert a '90-up 2-tank truck to a single tank, read this caption:


With the sending unit float arm in the empty stop position, resistance should be 15 ohms (below E). With the sending unit float arm in the full stop position, resistance should be 160 ohms (above F). The fuel gauge should read empty at 22.5 ohms and full at 145 ohms.
