To be on the cheap side will cost more than just draining your gas tank. **** IT OUT and analyze the gas. If you determine that it was good gas then put it back in the tank.

You can buy a **** hose (or 1/2 inch tubing) anywhere. Good Luck.

After water got in the engine oil what is best to use to clean up the inside of the engine?

There is nothing that you can use to absorb the water that can get everywhere because the absorbent on the markets are not of the right viscosity to reduce friction while the engine is running. The engine has to be running to get the solution everywhere. For example WD 40 is actually water displacer. Can you use it for lube? NO, it is to light weight and too expensive, Another water absorber is alcohol (ethanol) but it is too light. The answer is to drain the oil that is present, change it and run the engine to operating temperature. This will heat everything to the boiling point of the water and it will turn to steam. Leave the engine fill cap for the oil off, and after running it for about 30 minutes, you should change the oil again. You can use diesel fuel in the oil if you want to attempt to flush any globes out that the water may have created but don't put more than 1qt of diesel fuel in the engine and make sure that the level is not too high. In other words if the engine takes 4 qts of oil, use 3 and add the diesel. Run it and 30 minutes later, drain it.

Diesel. Reduce power lite turned on. Shut off engine and started back up - lite is off. Can it be driven?

Jerry, Drive to a good shop. So many things can cause reduced power light unfortunately. The first step would be to get the truck hooked up to a scanner/computer and have the computer scanned for trouble codes. One thing that you could try is to drain the water from the water separator that is mounted on the frame under drivers front door. If the PCM picks up on water, power is reduced until water is removed/drained. It could be an exhaust sensor that is reading faulty. Unfortunately from here its impossible to tell you exactly what the fault is because there are just so many engine sensor inputs that could cause your problem. Check the attached links, forums,instruction and guides, Good luck

I have a 2002 Dodge Ram 2500 5.9 liter 4 by 4 n truck started misfiring losing oil and don't know where the oil is going but the check engine light is flashing 20 times and it feels like its only running...

you need to take this to a shop. a flashing check engine light means that what set the light is causing harm either to the engine or the emission system. the lose of oil could be the truck burning oil if you have checked for oil leaks and have not found any.

I own a 2008 dodge ram diesel 6.7 has a lightning symbol in the middle of this ) ( and a check gauges message when this comes on.

The indicator you see is call a water in fuel warning lamp. ==== This a very important warning and you will need to take corrective action ASAP. ==== As a diesel owner,you need to know diesel fuel can attract moisture. When condensation (water droplets) collect inside the fuel tank,it will contaminate the diesel. ==== The corrective action is to locate the drain **** on the fuel filter and CAREFULLY drain the water from the bottom of the filter housing. (with engine off / key out) ==== The water in fuel warning light will go off as soon as the water is drained. ==== Use one bottle of RED Iso-Heet to remove any additional water inside the fuel tank.mustgo_54.jpg

Engine light comes on and wont go faster than 90 kms per hour back speed off and light gos off

the engine light is a run safe feature. it could meen low oil, fuel blockage, low coolant and, if diesel, water in fuel filter.
Check all levels, and if ok, it colud be something more serious like oil pump, water pump or oil filter.

My 206 1.9 diesel wont start

a diesel engine can only cutout when overheating, loss of diesel fuel and air leak in the fuel system. if you know how to bleed or ask somebody to bleed right after it stall, then start the car, if it starts immediately then it is sucking air.

Fuel gauge

Water in fuel
During refueling, it is possible for
water-contaminated diesel fuel to be
pumped into your tank. Your vehicle
fuel system is equipped with a fuel
filter/water separator to remove water from the fuel. The WATER IN
FUEL light will illuminate when the ignition is turned to START (as part
of the light function check) and when the FCM/HFCM has a significant
quantity of water in it.
If the light illuminates when the engine is running, stop the vehicle as
soon as safely possible, shut off the engine, then drain the FCM/HFCM.
Refer to Draining the FCM/HFCM and changing the fuel filters in the
Maintenance and Specifications section of this supplement for the
drain procedure. Allowing water to stay in the system could result in
extensive damage to, or failure of, the fuel injection system
