Adjusting the Fuel Float.

Guys,

I just finished doing some electrical work for my fuel pump. The pump was removed from the tank. I'm back up and running but the my issue is :

A Non Functional/ Wrong Reading Fuel Gauge.

Just looking for some confirmations before i go "digging" again. Laughing

Should the float be positioned outside of the pump housing in the tank?

Give a brethren a lil help nuh.. Thanks in advance

Slim........

I'm a tad confused as to what you're talking about.

Was the float and pump part of one assembly before, and u simply removed the pump? Then you would've only moved a couple wires and the float signal wires should still be intact.
The float shouldn't have anything to do with the pump anyway.

Now in this case, it's a bit of trial and error.

First off, do this in a well ventilated area away from heat and sparks, and have a CO2 extinguisher ready.

Make sure the slider is touching the rheostat at all times in it's upward/downward movement and that both contact surfaces are free of corrosion and other obstructions. You could try a very soft brass brush and spray with some electrical cleaner to clean the contact surfaces, and bend or adjust the slider as necessary.
Ensure that it moves freely and that there are no hard spots where excess pressure is applied by the slider on any part of the rheostat, or soft spots where fuel movement (eg. half tank or less on hard cornering) will breach contact.

With a known or reasonably estimated quantity of gas in the tank (even though a full tank is the easiest way, it only highlights the problem if the gauge is reading lower than it should. However, a half tank helps you to know if the gauge reads, higher or lower than it should), turn on ignition and examine where the needle on the fuel gauge points as opposed to where I should be, (eg. say u calculated half tank within a couple litres but the gauge is telling you that you're 3/4 tank)

Either way, once slider and rheostat contact is consistent, adjust the float so that the gauge reads to about your half tank of fuel.

way he said. with teh float out jack in the harness an move float up an down with ign on an see if teh gauge movin.if not check the float assenbly to see why
