My 04 dodge seem to have air in the fuel line how can I prime my fuel line?

Get a Haynes manuel or a Chilton and read. Usually you allow the vehicle to heat up until the coolant system activates the thermostat and flushes fluid from radiator into motor and motor coolant into radiator for cooling. Like most newer vehicles you will have a coolant retainer with a cap, remove cap and add coolant to its max line allow the engine to continue flushing inbetween with a work glove on squese upper coolant main hose, feel for any air. If retainer is full and you feel no air the coolant system should be primed. In certain vehicles there will be a shrouder valve that looks like a stem to a bike tire with a cap on it. Usually located on the thermostat housing. Bleed air from circulating coolant system threw the shrouder valve. When no is escapes and fluid levels are at max your cooling system has been primed. Hope this helps best advice get a manuel... good luck

I'm not familiar with that particular vehicle, but most diesel systems have a primer under the hood. You will need to pump that slowly until you feel some resistance. That will push fuel to the engine. The other pump may not be able to push fuel through until the system is primed.

If that doesn't get you running I would suspect a clogged fuel filter. Most Dodge vehicles have one on the frame. Just follow the fuel lines until you find it. There may also be one attached to the pump primer.

Changing that filter would my next action. Whether the pump is in the tank or added on outside the tank, you may still need to prime the system after the filter is replaced. Air in the line may cause it to stall, just reprime and start again.

Good luck.

Did you check for fuel pressure on the line from the tank while you had the filter off? Do you hear your fuel pump prime when you turn the ignition on? First I would listen for the hum of the fuel pump when you turn the key to the run position (not starting the engine) May have to get a helper and listen at the gas filler neck with the cap off. If you dont hear your fuel pump, check your fuses and relays. If the relay clicks when your helper turns the key on ( put your finger on the relay and ear down close to feel/hear the relay actuate)., and fuse is good, yet you do not hear the pump prime, I would say your fuel pump is shot.

If it is a diesel,check for fuel pressure coming off the direct drive pump hose while cranking the motor.

What are you priming it with?

Hello. If you remove the fuel filters and fill them with fuel, then hold the accelerator pedal to the floor while cranking the engine it should start. If that does not work, spray a little starting fluid (ether) into the air intake while cranking, just use the ether sparingly. This should get you going again, good luck.

It sounds like you are talking about a diesel engine as gas engines are self priming. Lift pump or primer pump may be defective. Check for loose fittings or lines and damaged o-rings at filter housing. Sounds like you are sucking air somewhere.

If you do not refill the filter housing after replacing the fuel filter there is another way to refill the housing.
after the filter is replaced and the cap is secured turn the ignition to run for about 5 seconds then turn to off. again turn to run for about 5 seconds then turn off. Repeat this about 8 to 10 times and then start the engine.
What happens is that every time you turn the ignition to run the fuel pump attempts to pressurize the line then shuts off. That is why you have to repeat the process.
While the truck is running the power to run the fuel pump comes from ecm. Some kind of safety function Dodge has built into the system so fuel will not continue to run if the engine is shut off.

the regulator is bad or clogged fuel screen or just leaking/loosing fuel prime. try to key it up a few times to build prime before starting. no matter u need to replace the pump if its not holding 55psi at the fuel rail.

most pumps wont pump until they have been primed,some pumps do something called "cavitate" or another term is "vapor lock"so try cracking the out going line,priming the pump with a little fuel in the incoming line and then placing it into the external container.when you get fuel coming from the outgoing line then you can cinch up the outgoing fittings.

you may have an air leak in the petrol line, probably where the fuel pump was changed.
the car won't srpay out petrol some time's but overnight the vacum in the fuel line ****'s air in & the system is not primed.
The only way you can check this is by priming the rail first thing in the morning by turning the ignition key to the point just before starting & you should hear the fuel pump run for about 4 second's then turn off the ignotion, wait for a few sec's & turn the key to same position, it will prime again.
Do that a few times & check for petrol leak's as the fuel will run back to the tank via a pressure valve, If you see a leak then you've found where the air is getting back in if there is no leaking but the engine start's then you will have to go over all the hose clip's in the petrol system.
If not that then get back to me !
