E90 Fuel Rail Line Hose Gasoline Leak
For about a week, I've noticed a subtle smell of Gasoline, it came through the Air Vents, and for a while I thought it was not my car... perhaps the car next to me I thought and during those few days, day by day, I started to get worried that I may have a gasoline leak. The Smell of Gasoline wasn't extremely intense but worrisome.
I haven't noticed any stains or leaks in my driveway, but I knew I would have to get to the bottom of this problem, because if left unattended it could be very dangerous.
Finally a couple days ago, as I am getting out of my car I notice a very strong smell of gasoline, unusually strong, and I knew I had to do something about it. I didn't see any gasoline, but boy could I smell it.

To my surprise the problem was very obvious, also extremely dangerous. Because I had just come back from a trip and my engine bay was "very" hot. I was afraid that a fire could start if left unattended, so I set off trying to unplug and clean the gasoline that was still leaking out.
Oddly enough, I could hear the problem, I heard a hissing, I think it was air escaping from the gas tank, I could hear it bubbling too, later confirmed when I removed the cover off the engine bay.
The Quest to Fix the gas hose
In my quest to get a replacement hose, I realized that this does tend to happen, and unfortunately I could only find it on
I found it cheaper at ECS tuning, here is the new link. Updated 3/5/2019

I recommend getting the hose from the dealer but it's $60 dollars cheaper at ECS tuning, so I'll leave it up to you.
From BMW South County, San Diego CA:
Part # 13 53 7 560 586
Price $157.21
How to Disconnect the Fuel Rail Line: Push the hose back into the connector, and push in on the Blue plastic, push in the blue plastic evenly, and the line slides off. It takes a little bit of practice, it took me about 6 tries to get it.
Push <--- back on the hose towards the spigot, and then Push ---> forward on the "blue" plastic, only, evenly. Then quickly pull out the hose.
How to Connect the Fuel Rail Line: Push the Fuel Line hose back into the spigot, and it snaps back in.
Be very careful, a hot engine bay and Gasoline could set off a fire.
When you remove the Fuel Line, Fuel will come out. I waited until my car engine was cold to start working on the car.
Tip: If there is NO pressure on the line, the hose can move freely back and forth freely, which would mean there is a leak in the line, BUT... if the fuel line is pressurize the hose will NOT move back and forth, and it feel solidly connected to the spigot, in the rail line.
Metal cover, protecting the Other end of the hose, below the Car |
I have to say that I struggled to disconnect the other side of the hose, because the spigot on the other end is made of plastic, but this is the trick...
Other End, Below the car |
I know you can find a tool to disconnect the hose, but I am no professional so I don't have it, so this is what I did:
Find yourself a wrench that is the same size as the blue part on the Hose,
Note: your hose may have a "Green" quick disconnect not blue like mine.
Now using a wrench, use the "U" part, put it on the end of the Fuel line hose, and while holding the hose, put pressure on the "Blue" quick connect, "Press IN" on the Hose, while you apply pressure inward for a second or two, then quickly pull the hose out.
It took me half an hour to do this, so don't get discouraged, because if you rush this part you will need to buy more than just the hose to fix this. It's going to feel like it's not working, but keep working it.
Take your time... note that when you remove the fuel line, FUEL will come out, so be prepared with a rag or "Pig mat" to absorb the fuel.
Support Jack |
This is where I put the support for the car, I had to remove a cover by the wheel well to get access to it. I left both the jack and the support stand on the car as an extra safety precaution, I think you should too if you are doing this. I ended up removing the wheel too, to get better access to the bottom of the car. I removed the Left side Driver side wheel.
I hope this helps you remove and replace the hose, it was a learning experience for me. But well worth it, because taking it to the dealer would have cost me easily $500 dollars.
If you have the time, I recommend replacing this part too, specially if you've never had it replaced before: OIL Filter Housing "Gasket". It's about $5 dollars, so well worth it in my opinion:
OIL FILTER HOUSING GASKET: I noticed a lot of oil coming from the Oil Filter Housing while looking for the fuel line, and I figured while I am here might as well do it too, you do need specialty tools to reach some of the bolts, plenty of video's online showing you how...
Part number for the is:

Good Luck with all your car work, and thank you for reading this far. Until next time.

I can't find the other end of this hose, can anyone help?
ReplyDeleteYou have to remove a rectangular metal panel, it's protecting the hose from debris from the road. it's only accessible from below the car, I have a picture in the article.
ReplyDeleteWorked like a charm. Purchase the line from a location in Nashville on Ebay for $84. A couple Notes: There is a cable holder on the top end that is attached with a torx screw and loosen hose clip at the back of motor. Also used a cable tie to pull new line in while pulling old out the bottom. There is a large rubber wear grommet and it goes on the bottom end of the fuel line. Thanks for the article.
ReplyDeleteThank you for posting
ReplyDeleteThanks for the article. I followed the link to ECS, and their stated compatibility for that line is the E90 335i. For your E90 330i (and mine) the part appears to be https://www.ecstuning.com/b-genuine-bmw-parts/fuel-hose/13537560586/
ReplyDeleteHello Mike. I'm having constant warnings on the dash (yellow car lift, CCID 216 - Fuel Pump Failure), but the car starts normally, doesn't misfire or anything. What can it be? Recently, the rail fuel hose was replaced, but it was giving the warnings before that. Can you help me?
