1996 7.3 liter diesel fuel leak?
Where is the leak at? Engine?
The diesel leak off is for getting air out of the system should you run out of fuel. It is very difficult to get the diesel engine restarted after running out of fuel as compared to a gasoline engine which is relatively easy. Once you have run your diesel out of fuel, the injectors must be primed for you to have even a chance of getting restarted. So, VW/ Mercedes owners, keep that tank about…
you can buy a fuel tank puncture kit. you need to drain the fuel tank so it can be completely dried. everything u need to fix the leak is in this kit. the kit costs about $10,but is well worth it, and if you follow instructions on the packet it works. i fixed leak in f350 diesel tank with same kit about 3 years ago and have not had a problem since
Restricted fuel filter, air filter caused by lack of maintenance. Internal or external fuel leaks. Check for an external leak in the valley of the engine, the cam driven fuel pump is in the center of the engine and has a tendency to leak. A internal leak would be a cracked head, check the coolant and oil for fuel contamination.
How can I keep a 1999 Dodge 2500 Diesel from dropping fuel pressure sparatically besides replacing the lifter pump and or relay?
if you loose pressure in system, you obviously have a leak. you need to find the fuel leak. make sure fuel filter is seated and sealing correctly,then examine all fuel lines from tank to pump, pump to injectors and pump to tank return line. if you have ever used ether to start the diesel, the ether ruins o rings in the fuel lines.the orings now being made of some inferior material
What would cause a dodge ram diesel engine to start hard when parked facing uphill but start easy when facing downhill?
Closely examine the entire length of the fuel line to see if there are ANY pinhole fuel leaks. Even the slightest amount of fuel seepage will result in a vacuum leak and that would cause the fuel line to suck air when the vehicle is facing uphill. If it's a small leak the action of the fuel pump could eventually overcome the leak, driving any trapped air out.
diesel dripping under a 7.3 powerstroke is usually caused by a small filter being clogged on the back side of the fuel filter housing is a small plastic part that will leak i cannot tell you what this part is called ,but this part can be replaced for about 60 bucks and with the use of some small alen keys,and a lot of patience insideis a tiny filter that that clogs up and causes fuel…
If this is an older vehicle, with carburetion, a ruptured diaphragm in the fuel pump could cause this. If this is a fuel injected engine, these engines use plastic fuel lines under the upper intake manifold. These lines become brittle with age and sometimes leak causing fuel to run down into the crankcase. If this happens you have to replace the lines, relatively cheap and easy fix.
A diesel doesn't not have a carburetor. What you are seeing is the fuel filter. Your leak is probably coming from the fuel drain valve on the back of the fuel filter. This part is a square plastic fitting held on with 4 screws with a plastic lever coming out of the top for draining the water separator. The O rings wear out inside it and start to leak. You can replace the whole part…
