Ok so not exactly a fuel line, but I want to run a methanol (or 50/50) line from a trunk mounted tank to the engine bay. I know you can run a line inside the car under the door sill, but I would rather route it under the car. At the moment the car is in a awkward spot, so I can't lift it easily to start looking. I want to run a bulkhead fitting in the trunk and run the line under the car and parallel to the fuel lines (if possible). Just wondering if there's a good spot to do this.

 

im in for suggestions... cause i've never done it.

but, i guess you could go under the seat and then down where the fuel pump is.

or just drill a hole in the trunk floor and dip down there somewhere.
of course, you would need to prep your hole with grommets... or something.

 

I was thinking of running it down where the fuel pump is, that might be the easiest. I ca use an AN bulkhead fitting in the trunk somewhere, It's just getting past the fuel tank that seems a bit hard. I'll get the car in the air in a couple of weeks and figure it out.

 

I would choose to run it through the evap system's gas vent tube hard line that's already there (and delete the evap canister). It's a 5/16" line IIRC and runs from the evap canister to the engine bay. Or really, run e85.

 

 

Canada has e85. There are stations in Vancouver area, Calgary, Ottawa, and I've heard somewhere around Guelph, ON too. And enough sources of e98 from race shops. There are many reasons to go e85 over meth injection even if access is an issue.

 

I'm well aware of the benefits. The car already has a flex sensor and can be ran on E85. LET ME HAVE MY METH GOD DAMNIT!!!!!!! lol.

In all seriousness, I appreciate the advice. However, I've ran meth for a while without any issues. This is just a better system i'm installing. As long as you're not riding the bleeding edge with your ignition timing, have a well deigned set up, keep your fueling on the rich side, and have your fail safes set properly, it can work quite well and be fairly safe.

 

Forgot to update this. Just in case someone ever has this question (even though its pretty obvious once you get under the car). You're able to run the line up against the body of the car, around the one side of the fuel tank. Then I just ran it beside the other fuel lines up to the front of the car.

i this is before I secured the line with stainless rubber cable clamps.
