SOURCE: 90 GMC PU brake line over gas tank has leak-need diagram

no you can cut and reroute the line ive done it in the past many times. just remember more line means more fluid so after you bleed it check the level again after a week or so.

SOURCE: Have a 1995 GMC Sierra Truck. Gas is leaking from

chances are your leaking from the gas line from your fuel tank to engine. More than likely the pressure line, but it could be your return line as well. To figure this out you would need to take your fuel tank off the vehicle, and inspect the lines. look for rust and cracks. Rust is a good sign of weakness, and chances are this is where your leak is. Hopefully this helps.

SOURCE: GMC Jimmy gas filler neck leak

Replace your filler neck. It's not hard and when you buy the new one, installation should be obvious and rather straight forward.

A fuel leak is not something to take lightly and it will get worse over time.

Most fuel systems are pressurized (that's why you'll sometimes hear a hissing sound when you open your cap) so if your filler neck is leaking it can throw a code.

Car starts but as soon as I press on the gas the car stalls


Just on the off chance, Be careful that this is not a leaky battery, this fluid is a corrosive acid and will burn and eat away at anything it touches.
Some quick things to check...
Check you have plenty of gas in the tank, and check the gas tank air vent for blockages.
Check the Air inlet and Air filter for any obvious obstructions
Check your exhaust pipe for obstructions

Maybe its a choke problem, or some other carburetor problem.

Replaced thermostat on pontiac sunfire now there's smoke coming from coolant tank


Sounds like you have a leaking head gasket or damage to the engine from when it overheated.
A leaking head gasket can cause compression to leak into the cooling system and pull coolant into the cylinders which is burned out the exhaust. It does not have to leak into the oil.
A shop would check for exhaust gas in the cooling system and run a compression test on the cylinders.

If the smoke has a sweet smell to it then it is coolant from an internal leak inside the engine like a head gasket or other source. To confirm that you have a leaking head gasket have a shop problem the coolant recovery/surge tank with a gas analyzer for the presence of hydrocarbons in the coolant tank, this indicates for sure that a head gasket is the cause of the white smoke.

Why does it sound like coolant is getting flushed back into the coolant tank? Like when I start up the truck to warm up, I'll give it a little gas. Then I hear a leaking sound by the coolant tank but...


If there are no leaks this is fine. The coolant contracts as it cools over night and this noise you hear is the system equalizing itself while coming under pressure from the forces of the water pump, radiator cap spring, thermostat spring and any other expansion - contraction issues involved in the cooling system components. Hope this helps ease your mind. Let me know. Thanks. PS be sure your system is filled with the proper type and ratio of coolant to water for you areas temperature ranch.
