Understanding The Dangers Of Installing A Diesel Fuel Shut Off Valve Backwards

Posted by on Dec 1, 2015 in Uncategorized | Comments Off on Understanding The Dangers Of Installing A Diesel Fuel Shut Off Valve Backwards

If you have a diesel vehicle with a shut off valve attached to the fuel line, then you may need to replace this valve at some point as you own the car. This part is responsible for stopping the fuel from running to the engine. You will likely know that replacement is needed, because the car will likely continue to run when you turn the key to the off position. To fix this problem immediately, you can manually shut off the valve by pressing the small lever on the side of the part or the housing covering it. After doing this, get a new part from your local auto store. If you decide to change the valve, make sure to consider the information below about the dangers of installing the part backwards and how the diesel engine can be shut off if you do install the part backwards for some reason. Dangers of Installing A Diesel Fuel Shut Off Valve Backwards If you are familiar with car parts, then you may notice how the shut off valve was situated when you initially removed it. However, if you are a novice, you may forget to consider this. The diesel shut off valve works on a vacuum type of fuel system where the air will be sucked through the fuel lines with natural pressure. Unlike other types of engines that rely on electronic fuel pumps and sparks, the fuel will continue to run to the engine even when the car is shut off. The shut off valve keeps this from happening by pulling on the shift linkage to downshift the car until it turns off. A small lever on the shut off valve will complete this task. Unfortunately, if you accidentally install the valve improperly, shutting off the car will actually push the lever attached to the shift linkage. This can happen if the device is connected on the wrong side of the linkage attachment. This will cause it to shift upward and the engine will throttle and produce a great deal of power without the vehicle moving. This can cause the engine to quickly overheat, because very little air will be moving through the engine compartment to cool it. If a gasket or the engine block cracks due to the heat, then this may be an extremely expensive fix. Emergency Shut Off Procedures If possible, take pictures as you remove the shutoff valve from the shift linkage attachment so you can reference this as you add the new device. Also, keep in mind that you can shut off the engine fairly quickly in an emergency if there is a need. You can do this by cutting off the air to the engine. Fuel and air is mixed together while an engine is running. Without enough air, the engine will stop. Before you start your car after replacing the shutoff valve, remove the air filter from the engine air intake. This will allow you to plug the intake with a rag for a few minutes if your car throttles uncontrollably when you turn it on. Also, some vehicles will come with an emergency air intake shutoff valve for this reason. Search for one of these valves around the air filter. Do not panic and force your hand over the intake though. Suction is strong and this may cause a...

Microfiber cloth Cotton swabs How to apply touch-up paint – a step-by-step procedure 1. Choose the correct touch-up paint pen for your vehicle – it is important to purchase a paint pen that matches your vehicle’s specific paint code so your final work doesn’t stand-out. This code specifies the exact paint color as painted by the manufacturer. Paint codes are usually a series of letters and digits, but each manufacturer’s code format is different. To locate your vehicle’s paint code, the first place to check is on the driver’s side door edge or the door jamb. Most manufacturers place a label on either of these locations that contains paint information along with several other bits of information. Much of the time, the label will bear an abbreviation, such as EXT PT, or similar wording. However, some auto makers have no explanation for their code, so you will need to decipher where and what the code says. For help with understanding the code, contact a dealer for your specific make and ask to speak with the parts or collision repair department. If your vehicle has been repainted in a color other than the original manufacturer’s specification, then you should contact the facility that did the repainting. They should be able to provide you with a close match to the factory code. 2. Evaluate the damage – inspect the damage on your car under a strong interior light or outside in daylight. If you see shiny metal at the lowest part of the damaged area, then you will need to use a primer before painting. If the damage is white in appearance, then the damage has not penetrated to the metal, and primer shouldn’t be needed. 3. Clean the damaged area – with a clean microfiber cloth, apply a generous amount of rubbing alcohol to the damage and the area immediately surrounding it. Rub firmly to remove any traces of wax, oil, dirt or other residues that might affect your paint application. If the cloth isn’t able to reach into small crevices, use a cotton...
