gas gauge

[stallion3599]

My explorer stays on e all the time, I have to judge the gas by the miles.
I heard a couple other people say they were having the same issue. I do not know if the fuel pump has ever been replaced as the float can be bent but it usually gives crazy readings like empty at a quarter tank ect. any suggestions tips ect are welcome.

drain tank (wait till almost empty)

Replace sending unit, they go bad get hole in then.

Have fun. Personally, I'm avoiding all that fun.

Sending unit is part of the fuel pump (usually you buy an "assembly")..

I would first make sure you don't have some other wiring issue. Take the sending unit wire off the top of the tank and ground it.. while grounded the gauge should read over full. If it does then the wires to the gauge and the gauge seem ok, and you are back to the sending unit..

As it was already said (and there are threads on this for more instructions) you have to drop the tank to change the fuel pump assembly which has the sending unit. Some people cut access panels in the cargo area to keep from having the drop the tank...

2 methods of doing the sending guage / pump ( same unit ) .

a: drain as much gas out and then drop the tank
pros > can clean the tank very good / inspect for damage or potential
damage to tank
cons> kinda somewhat hard to do if you never done it (tank is akward)
you got to lift the truck up high enough to get the tank out (i used
railroad tie pieces under the rear wheels) / skid plate is some what
heavy / you really need 2 floor jacks to reinstall every thing ( a lot
smoother if i had another one to use to help stablize the tank and
plate as they went in postion .

b: cut a access hole in the cabin to get to the pump

pros> you dont have to drop the tank .

cons> you will create a lot of metal shaveings that get every where inside
and maybe the tank / now you got a hole inside the truck body and
needs to be sealed to keep out water and keep away rust /you
have to reinstall the rear seats and carpet in the cargo area.


just remember to buy a GOOD pump and not a cheapo unit,i made that mistake and had to do mine twice .

the connector for the pump is located on the left frame rail almost inline with the axle (small keeper that hold the harness to the frame is kinda bugger).

if you have never replaced it or do not know if it has ever been replaced chances are that the locking ring and o-ring that goes under the pump plate needs to be replaced .my ring was not to bad but when i removed it useing a concave punch and hitting every tab as i went to un-lock it ( easier that way and you don't destroy it in the process) . i just cleaned it up a little and got any loose rust i could find and spray painted it rust fighting paint ....but the o-ring was toast but most if not all new pumps come with the ring in the box .

also when you take the fuel lines off the pump ..mark their direction on how they came to the tank/pump connects ( don't want to install a new pump and be off 2-3 inches in directions and have to either re-do it all over again or trying to get your plastic lines to stretch then have a break in them)
