Slant Six Fuel Mileage?

Before I filled her up Monday the gauge read 1/4 tank. The pump kicked off after 6.6 gallons and the gauge read full? So the new sending unit is the culprit. At least it "kinda" works! :BangHead:

mine does the same thing.....those electronic boxes work to correct the problem.....The best ones are the ones you can program for 4 positions Empty 1/4 1/2 and Full......
