My exhaust looks good no unusual color and is mostly smoke free. 171 1 1 silver badge 3 3 bronze badges.
Still working on it but cold enough to freeze the balls off a pool table here and Im not heating up the garage.
Air in fuel line symptoms. Symptoms of air in the fuel would be a rough running engine and low power. Depending on how much air is in the fuel determines how rough the engine is going to run. The more air in the fuel the rougher the engine runs and the lower the output of the engine.
What Are the Symptoms of an Air Leak in Fuel Line. Here are some symptoms of air leak in the fuel line. One of the symptoms of air stuck in the fuel line is a low-power engine.
The engine will run rough. That is it would turn fine then start losing RPMs Revolutions Per Minute. Does air in diesel fuel line have symptoms.
If it is a diesel then white smoke and rough running is one of the symptoms of air in the injector lines. Thats pretty much like running out of gas which it is cause when the carb bowl is full of air the engine quits running. In this way what are the symptoms of having air in the fuel line.
Air bubbles in a fuel line can lead to stalling hiccuping or refusal to start. Keep your fuel lines free of air to help keep your car running smoothly. How do you bleed air from a fuel line.
Here are a few ways to remove air from a fuel line a truly problematic experience. Air bubbles in a fuel line can lead to stalling hiccuping or refusal to start. Keep your fuel lines free of air to help keep your car running smoothly.
When you change a diesel fuel filter run out of fuel or disturb the fuel system air is trapped. When you try to start the engine this air acts as a lock preventing the normal supply of fuel into the cylinder. Here are the steps to take in bleeding air from a diesel fuel system.
Observe powerful flow from fuel line. Manually actuate the lift pump you may have to move the crank position. Observe power pulses of fuel into the bucket.
If you dont get powerful fuel flow on both manual cranking and starter cranking its the lift pump. You have the classic symptoms of a bad lift pump. Poor high speed performance.

Fuel lines containing air can cause the engine to not run properly. Generally air is introduced to the fuel lines when there is a leak or during fuel draining for equipment storage. Very little mechanical knowledge is required when bleeding fuel lines.
The air getting in the fuel line from the filter is either the plastic sensor assembly on the bottom of the filter or the filter head itself or both. One of my rigs has this issue as well. Still working on it but cold enough to freeze the balls off a pool table here and Im not heating up the garage.
Basically your using air to force fuel through the tank and to the filter. See if you get a constant unrestricted flow without interruption. If the fuel trap fuel gauge sending unit is bad replace it the gauge problem can be fixed by lining it up right in the tank.
Does this sound like perhaps I have air in the fuel line. My exhaust looks good no unusual color and is mostly smoke free. Follow asked Jan 19 16 at 2329.

The car now starts btw which is good but im stil not usin it until we know wot to fix. If it is getting no fuel to the pump due to air in the line the pump cannot push the existing fuel forward. If there is not an actual leak in the pump the pressure could be maintained for awhile without actual flow.
Sounds weird maybe but its a real life scenario. There are many symptoms of diesel fuel system leaking air which include. Red smoke out of exhaust.
Black smoke out of exhaust. What Can Happen When Theres Air. Symptoms are sometimes there is a lack of power somwhere over 2k if I put my foot down not a great deal happens but acceleration lower in the rev range seems OK.
Also starting when cold can be a bit difficult. I think both of these issues are due to air in the fuel line. When the car is running I not only see air bubbles but at times nearly.
Crawl under your truck and look for rust on the fuel lines. If its heavily rusted it could be the leak current leak or it will be a future leak. The pick up unit from the fuel tank is prone to rusting out.
Another symptom of a bad or failing fuel hose is visible fuel leaks. If any of the hoses break down dry up or wear out enough they will leak fuel. A leaky fuel line will produce either drips or in more serious cases puddles of fuel underneath the vehicle.

If you ran the engine out of fuel you know what caused it. The air in that clear tube is a symptom not a cause. Its the return line to the tank returning fuel the injection pump does not need.
When the injection pump isnt getting the fuel it needs there is nothing to return to the tank. Strong fuel odor engine misfires and decreasing power. One of the first symptoms of an issue with the fuel return hose is an excessive fuel smell.
If there is any sort of issue with the fuel hose either a leak or some sort of kink that blocks the flow it may cause the vehicle to produce an excessively strong fuel odor from the engine. They suck in air if they are bad when the engine is running. Replace these if they are bad with some good blue fuel line NAPA sells it.
No need to pay for the pre formed OEM fuel line costly and may be hard to find. The blue fuel line will not kink and will more than likely outlast the truck.
