Nutmegger, Sort of had the same problem guage, would go from full to empty in about 100 miles and then take another 200 before the low fuel light came on Could be the earthing (grounding) is abit duff. Try cleaning all the electrical contacts under the boot (truck) floor first. You can lift the floor covering the access to the tank guage and pump and do the same thing. You could take the guage sender assembly out of the tank and move it around and see what the guage does. If no success you could use a multi meter to check the resistance of the guage float when moved from full to empty, making sure there is no "dead" spots. The resistance should change smoothly as the float is moved. Check the voltage supply at the guage sender unit. If no luck there the wiring connected to the dash could be loose/dirty, depending on the age of your car there may be a resistor across the contacts on the back of the guage. Taking it out is a pain, checking the sender is easier which is why I did that first. Finally tracked two problems down in my car, bad earth in the back of the car and a poor connection to the guages (temperature gauge always seemed to read low) The tank is plastic and unless punctured should be ok Good Luck Malc Scotland nutmeggernopsameja.com wrote: > I don't know what it is, I fill up it seems okay. > Somedays it reads empty after a hundred miles > Somedays it stays on full after a hundred miles > It has no rhyme or reason, like most Saab problems > I'm going to run out one day if I don't watch it. > So do you think the float got stuck or lose? > I need a new tank? > Just wondering........... > > Sent via Deja.com http://www.deja.com/ > Before you buy. > Sent via Deja.com http://www.deja.com/ Before you buy.
