Captain... she's leaking - BMW Forum

My BMW is leaking gas somewhere underneath the engine

: .
This only happens when the car is turned on, if the car is not on, then little to no gas is leaking (I know it's gas cus I crouched and smelt it

)

would this be a problem with the fuel lines or fuel pump?
and how much would it cost to fix and where would be the best place to go.

Keep in mind it's lowered so I don't have easy access underneath her.

pronbably not the fuel pump unless u smell it from the rear...or while in the car...could be lines and/or fuel injecters...

alright so i assume there is a puddle.. hopefully it is just a broken clamp on the fuel filter or somehting. Worse case would be a leak in one of the fuel lines somewhere. Wouldnt think a leaky injector would create a puddle under the engine.. I would be hesitant to drive around town like that. Take a look yourself if you can. IF it is coming from the fuel filter then get 2 new clamps and a filter and change it out. Save yourself money.. And the fuel pump is in rear so that is eliminated off the bat..

got any pics of the underbelly of my car or close to it so that I know what I'm looking for?

Park it over a clean piece of cardboard and take note of where and how much the leak is this may help in finding it. You did mention that your car is lowered, this may have caused a fuel line to rub and wear through. Furthermore if BMW does fuel lines like other cars I have screwed around with there will be 2 fuel lines. One takes fuel to the injectors, the other is a return line to the tank. These are most likely steel lines bent to conform to the undercarriage, the last time I did this job the lines ran above the tranny!!
This was not a beemer though.

Good luck with it.

Got a mechanic to take a look at it.

:

guy said that the fuel line is leaking in the engine bay.
He mentione that it is "hidden" from access by the intake valve,
and that the only way to replace the fuel line is to remove the
intake valve which will take 5-6 hours and he wants to charge me
by the hour

:

is this mechanic just bull s***ing me? or is the fuel line really that hard to get to that the damn intake valve must be removed.

If he's saying "intake valve", he's not much of a mechanic. The intake valves are inside the engine. He's talking about the intake manifold and the line could very well be under the manifold. If you are reasonably mechanic-minded, give it a try. If you are uncomfortable in any way, I would check with some more mechanics in the area
