How can I diagnose & fix a fuel leak in a 2005 dodge caravan?


check to see if the fuel filter is leaking at line connections as the filter is on top of the tank. if so replace the filter. check the seal for the tank unit that seals this to the tank. being this new it should be good its more likely the fuel filter.

Gas leaking front passenger side of ford windstar


Have you looked under the hood? (I don't mean to sound like a wise guy.) There are two shiney metal pipes one on the front of the engine and one on the rear as you look at it from the front. They run from right to left on the engine. These are the fuel racks that feed the fuel injectors, (assuming that you have a 3 litre or larger v6 engine). These can concievably rust at the left, (passenger), end and blow gasoline out the passenger side. It is also possible that gas could be leaking anywhere on the engine and roll off the passenger side of the engine or if the fuel line on the driver's side has rusted over a cross member of the frame and possibly roll to the passenger side. Also, there is pretty good pressure on the fuel line when it is running. If there is a rust hole on the right side of the line itself, it could spray to the passenger side, hit something and drip off from there. These are just possibilities. Good luck. Jeff M.

The tank is leaking and running down to the exaugst. what might me the problem? i can also smell it on the passenger side of the car. thanks


Any fuel leak is a problem and down the exhaust is a major problem that needs to be addressed. Replace the gas tank if it's the gas tank leaking but most likely will be a fuel line leaking from corrosion. Replace the affected are of the fuel like that is corroded and leaking.
Thank you for using fixya and be safe.

Gas leaken new tank 94 4 runner think its fuel pump seal but dont wanna drop tank if dont have to found axcess pannel under rear passenger seat but dont see fuel pump to see if thats where its leaking from...


If the smell is coming from the back of the vehicle then it could be leaking from the return line or the filler hose. I would check the fuel filler hose first since you can probably get at it wihtout dropping the tank. You might be able to get to the return line as well which is a small hose that goes to the tank from the fuel pressure regulator to return unused fuel. If the smell is coming from the front of the vehicle I would inspect all of the fuel lines and the inline fuel filter if you have one installed and verify that none of the hose is damaged and all clamps are tight. Check your injector rail and make sure it is not leaking where it provided fuel to the injectos and check your injectors seat to see if there is any evidence of fuel leakage.

If you can't find any leaks in those locations then you are gonna have to drop the tank and check the pump.

2000 ford windstar gas smell on the inside only no gas leaks already changed the fuel filter the pcv valve is fine as well .where is the smell coming from? and why is it only on the inside and u can't...


Check and see if you have any gas on the ground after you park your car. Check around the gas tank and gas cap. It's possible that the fuel pump (which is in the gas tank) has hoses that may be leaking. If this is a slight leak, it might only manifest itself via a gas odor into the trunk or passenger compartment. It might be a good idea to put the car on a hoist and follow the fuel lines from the engine to the fuel tank. There should a one line that takes the fuel from the fuel tank to the engine and another that brings back the excess. There should also be another line coming out of the fuel tank that is for venting. Unfortunately, the fuel pump and hose connections are not easily accessible and require either removing the gas tank or cutting a hole in the trunk to access it. You should definitely take care of this soon as leaks don't get better, only worse and it is a potential fire hazard. Good luck!

Smelling gas fumes in passenger cabin. Cannot detect any smell under hood. Does it have a cabin air filter ?


There are rubber gas line hoses under the hood & after a number of years they tend to leak ever so slightly. They are under the hood to the passenger side. You may need to replace these fuel lines. There should be a cabin filter but you must take the wiper motor screen off to get at it & it is on the passenger side. Good luck!

The filter is inside the tank. could have a fuel leak, thats why it smells. I would ck it cold, turn the key so that the fuel system pressurizes, then follow the lines and look for a leak. ck any joints, and at the injectors.

1990 toyota 4 runner smelling gas.


Thank you for allowing me to assist you with your problem.
My experience with this particular issue leads me to believe that you probably have a rusted fuel line or lines at the top of the fuel tank, assuming that the fuel lines are OK under the vehicle. This is a very common problem. There is a bracket there that holds the fuel pump inside the tank, and the fuel lines that are welded to the top of this device are wont to develop pin-holes over time and age. Very noticable when driving, most likely the line going to the engine is the culprit. Get under the vehicle and see if there is wetness at the top of the tank. If so, you will need to drop the fuel tank and replace the fuel pump bracket. I hope that this helps you solve your problem.

Engine turns over fine, won't start


the fuel line is located along the passenger side of the frame, and there is several links/splices, including the fuel filter, located just behind the passenger door. check along those lines. My truck wouldn't start and I had a small leak, when I fixed the leak, it started and ran fine. hope this helps
