Don't do it, much better to run them under the car or use your washer fluid tank..

It is not difficult to route the meth hose and wires under the driver side doorsill protector, at least not on a coupé. I don’t think it is a bad place since the stuff will be protected to some degree. You need to lift the protector and remove the clips, and secure the hose and wires with tape to the doorsill so they doesn't get trapped under the clips when the protector with clips is put back. You also need to loosen the panel for the hood release mechanism, which is secured by a screw on the release handle. The LH rear seat needs to be removed as well. I did it on a friend’s car and it turned out quite well.

Also there is nothing wrong with running the lines inside. The only downside would be inhalation of methanol for long periods of time but you will smell it if there was a leak so it is therefore not a problem.

it seems dangerous but meth in general is so the risks are the same witchever way you look at it.

Anyone run meth lines through the interior of an e90?

The problem is if you get a line leak, you have a ruined interior and you will likely destroy the metal body of the car in that area. I have strongly suggested againsts doing this since day 1.

Running under the car is not difficult. There is a cold side (drivers side). Follow the white rabbit (white transparent line, see the DIY's). You can even do it on ramps. I'm 6'4". >200lbs, and backed up on ramps, did the back half, then put the ramps on the front and ran the lines the rest of the way. Not the most comfortable way to do it, but not too bad.

I used RHino ramps rated for 12,000 pounds. Be careful!

One end of the car on rhino ramps, the other end on jack stands. Being able to use a creeper to go from front to back is nice for routing the line.

The methonal would have to be sitting still for a very long time for it to degrade the metal body, let alone you still have to go through the foam insulation. You would easily notice a leak of that size before any damage would occur. As for the carpet you can just get it cleaned if it comes to it. To each their own though the meth kit will work just as good either way. Good luck with your install.

At first thought it seems like a bad idea, but on the other hand windshield wiper fluid is often run through the interior...

I had one customer that wanted it that way. I pulled all the panels along the driverside including the b pillar and ran it along the corner of the body. No places for it to get caught or chafed up, and I ran it through the rubber grommet up by the drivers feet. It was a clean install and no issues.

From the recent DIYs i thought most people were routing it through the interiors? I was planning on running it through the interior. I used to do car audio and still do it on the side from time to time, and am very familiar with how to remove panels etc.

i'm sure a lot of people are well meaning and really concerned about making you happy and comfortable with this type of decision. but lets look at the plain facts.

1) there is a reason why fuel supply lines are routed outside of the passenger cabin (this includes the door thresholds -- ie door jambs) unsolicited intrustion in this area is stuble.. and not dramatic .. and leaking fuel line (whether gasoline or diluted methanol and water) will not let you know whats its doing -- inhaling methanol over a extended period of time is not healthy and will lead to dizziness --- ever ride around in a car with a fuel leak in the cabin? try sniffing some meth for a while and see if your judgement is impaired.

2) you have no control over your environment in a crash scenario... if the line is ruptured and an evaporative fuel source is in the cabin area how do you minimize the effect? methanol vapor, electrical power sources all in one area.. do you want to be inside for that ride?

there are automotive principle that are not followed by the local "shade tree" mechanic, and with the internet -- there are a million of them, ready to give you free advise and walk away when something bad happens..

you will never get a better chance to implement safety and performance, than now... follow good principles, not the ones that are the easiest .. that can cost you dearly at the end of the day ..

Methanol burns clear so you could be cooking inside your car and people watching wouldn't even know. I would be very carefull handling that stuff.
