If it has the factory dual tank option with a electrical selector on the dash... switching a factory electrical fuel switch.......you could remove one tank completely.....either one and it won't care.

As long as you select the tank with the fuel on the dash switch.

I have 2010 mitsubishi endeavor milage is only 54695 it burns lot of gas


1) you might want to check the fuel filler tube to see if there any rust, resulting in fuel leaking out whenever you filled the tank.
2) check the fuel tank fill-up hose (sill hose) might have a hole- causing fuel leak when filling up the gas tank.
3) you might want to contact your dealer, there was a recall regarding the tank filler pipe and cap problems.

Gas leak


Being a 93 model, I would suggest inspecting your fuel tank, rubber hoses in or near the tank, all fuel lines, look for a hole in tank as well. Rubber hoses eventually dry rot, causing leaks. And your tank can and will rust through eventually. This is a VERY dangerous situation as any little spark can cause a fire.

Ford f 150 dual gas tank drawing from both tanks at the same time


Replace the fuel deliver valve, it is under the truck on the drivers side, it is a black plastic canister with lots of plastic lines going in and out of it. If you find this is the problem disconnect one line at a time, don't take everything off at once and mix them up.

Does the '89 Isuzu Trooper II have a gas tank


Depending on how good the guage is, when the yellow light comes on telling you that your fuel is low, you have approx 2 gallon left in the tank. It is never good to run on a tank that low due to heat buildup of the pump which causes pump failure. The gas acts as a coolant for the pump.

My 1991 dodge dakota v6 2 barrel is using way to much gas 150mi per 16 gal tank what is the cause


check for fuel leaks. from the gas tank, to the fuel lines, to the carb. i assume its an electronic throttle body 2 barrel. i have seen those leak internaly from the inside of the carb/throttle body causing exsess fuel to be used. you could also have a very bad fuel/air ratio going on there. could be bad o2 sensors. but i would start with the leaking fuel first.

Gas is being forced out of the fuel tank when the vehicle is running.


A defective fuel pressure regulator (located on the fuel rail) may have blown the gasket on the
fuel pump (located in the gas tank).
Another thing to check - the car's computer may have posted
an error code from the fuel tank pressure sensor.. I'm not sure, but if this sensor shows pressure
building in the fuel tank, rather than let it explode its seals, the sensor may intentionally leak fuel
in order to relieve the internal fuel pressure build-up inside the fuel tank.

On the fuel rail (supplies fuel to the fuel injectors on top of the engine), there will be a Schrader valve,
which is your connection to connect your Fuel Pressure Gauge to your car's fuel rail.
Give it a check, but put a shop rag around the connector as your screw it in - fuel (and fuel
pressure) will leak as you install the fuel gauge.

You may get computer diagnostic codes P0158 or P0159 - see below for interpretation.
Note that the PCM is the Powertrain Control Module, which is the car's computer.
Also "TP sensor" is the throttle position sensor.
---------------------------------------------------------------------------------------------------------------------------------------
Trouble Code: P0158

Meaning: HO2S-22 (Bank 2 Sensor 2) Circuit High Input

Possible Causes:

Fuel system is too rich (fuel pressure too high, fuel pressure regulator leaking, or one or more fuel injectors sticking/leaking)

HO2S element is silicon, water or fuel contaminated

HO2S signal circuit is shorted to system power (B+)

HO2S signal tracking (water intrusion) in the connector causing a short between the HO2S signal and heater power circuits

PCM has failed

----------------------------------------------------------------------------------------------------------------------------------------
Trouble Code: P0159


Meaning: HO2S-22 (Bank 2 Sensor 2) Slow Response

Possible Causes:

Exhaust leak present in the exhaust manifold or exhaust pipes

Fuel system is too rich (fuel pressure too high, fuel pressure regulator leaking, or one or more fuel injectors sticking/leaking)

HO2S element is silicon, water or fuel contaminated

TP sensor element broken (can cause false acceleration event)

Filled truck up with fuel and fuel guage stoped working


There is a TSB for this issue ( TSB 08-2-9 ).

The problem is high sulfur content fuel will cause a problem with the fuel level sending unit, and cause it to read incorrectly.

The 2 times I had this happen, I was not at my normal brand fuel ( had it happen with Shell fuel both times ).

I fueled at 1/2 tank with my normal brand, and then after another 1/2 tank fueled again, and the problem went away.

If you want, the TSB lists new revision fuel level senders, that you can drop the fuel tank, and replace your exiting one with to cure the problem.

The correct P/N depends on your truck cab & bed config, and options

I want to replace my fuel pump in my 2002 ford ranger truck. Do I have to remove the gas tank? I was scanning the internet two days ago and found a step by step instruction for removing the fuel pump and I...


first of all, if the pump is not working there is no used to replace the hose. the amount of ethanol in the gas is mostly regulated by the government so if there is a problem then people will know about it.
to replace the pump you must remove the tank. you can do it by yourself if you have jack stand and a good floor jack.
put the rear axle of your vehicle on the jack stands equally then put the floor jack under the tank with a piece of wood to support it, then lose all connections such as straps, wires and hoses.
lower the tank then pull it out from under and you can work on removing the pump. hope you did not have much fuel in the tank, good luck

I got gas leak coming from the fuel line right above my fuel pump but nothing is broken, craked or loose and the pump is in perfect condition.. could a clogged fuel filter be the problem? its comin from...


First off, what kind of vehicle do you have? I assume it is one that has an electric fuel pump in the gas tank, so that is what my answer will be geared to.
On the gas tank there are several lines. The most important ones for this conversation are the ones that deliver fuel to the engine and the one that returns the excess fuel back to the tank. They are usually different in size.
The larger one delivers the fuel and the smaller one returns the excess fuel back to the tank. Either one may be the culprit in this scenero.The tank is usually connected by a high pressure flexible fuel line to a stainless fuel line resembeling a brake line. At times this flex line may develope a leak for varrious reasons. It could be something rubbing against the line, it could be the crimped connection went bad and is leaking, etc. If it is your flex line, which it probably is there is a repair kit you can purchase to fix it. I have only been able to find this repair kit at NAPA. I've tried many auto parts stores and they are the only ones that carry it. The use of it is very simple actually. You find the leak in your line, which by the way is harder than it sounds and usually involves removing the gas tank. In which case you will need a special tool to disasemble the gas line from the tank. Once the leak is located you cut the line. You then have to place the remaining flex hose in boiling hot water for at least 10 seconds, which makes it soft and insert a splice fiting into it. When the line cools, it will shrink tight on the connector. You the do the same with the hose that came with the repair kit. Then do the same with the other end and install the fitting which connects to the gas tank. You should now be in business.
BTW. I have to do this very thing tomorrow.
Good Luck! and let me know if this helps you.
