Question about 1989 Ford Econoline

1 Answer

I have a 1989 Ford E150 van with duel fuel tanks. I can switch from one to another with no problem, BUT I do not get a fuel gauge reading when either tank is on. Is there a fuse for the fuel gauges and if so where is it located. Every thing else works fine. Thank you for any help you can give. Crawford

The fuse would likely have more things included than just the fuel guage.There likely is the fuel pump relay in-line too,but that also affects a couple of other things,1 being the ignition coil,and you probably would have no engine run at all,so that's eliminated.Since there are 2 tanks,the guage itself would be the most likely bad component as both of the tank sensors going bad at once is about equal to 1 shot,2 kills.If you ever had a situation where 1 tank would work good with the guage and the other would not,then I would say eventually they both failed.Since you did not mention that,and would definitely notice it,it has to be the guage,if both all of a sudden stopped working.You should check the connection involved first before replacing the guage.A connector or wires on/to the guage.Although it isn't likely that a wire or connector would just disconnect,stranger things have happened,and easily could save $100 or more if it did.Greg

Where is the fuel pump located on the duel gas tanks?

Hello Gary - There is a low-pressure pump in each tank of your Ford F-350, along with a high pressure pump in the frame rail. The low pressure pumps inside of the tanks are part of the fuel sending unit assembly for the fuel gauge. I hope this information was helpful.

Call a dealer with your VIN number and ask if there is an open recall for your van. Report back results.

No fuel guage readings,cant use front fuel tank vehicle stalls out,fuel coming out of front fuel tank cap when running,1988 ford e150

im thinking that this has dual tanks and one of the selonoids that switch the tanks have failed, Its the fuel coming out the cap that is tough. does it flow out the cap like its over full or is it just a couple splash drops like rain drop? does the other fuel tank read the same fill level while this is happening?? Cause the only way the front fuel tank can get full is if the fuel is being pumped into it by means of the fuel in the other tank. Now im not sure if they run return lines on that but if they did and the return line is near the cap i could understand the couple splash drops. Vehicle stalls on the front tank because the selonoid that opens and closes allowing fuel to be picked up to the motor is bad or the electrical switch or wiring is bad. selonoids are located under van close to the front of tank.

Duel fuel tanks

you will need to replace the front intank fuel pump. the check valve in the pump has failed and the rear pump is pumping fuel into other tank ,

Front fuel tank will not work

You have duel tanks with a fuel pump in each tank. You also have a fuel pump on the frame rail after the "tank selector". This device only holds a fuel filter that protects the main fuel pump. When you select front or rear tank on the dash, you are selecting which in tank fuel pump will operate. You can check the in tank fuel pump by listening for it to "humm" when the key is turned on..The in tank pumps only feed the main pump and cannot run the engine on their own. Hope this helps

Fuel Gauge not working

The switch that you use to change tanks is probably faulty - the switch supplies power for the sending unit in the tank, and to the transfer switch for the gas lines - use a meter to check it
