Where to Run Meth Injection line through firewall?

scutzi128 · 04-29-2008, 02:21 PM

Hey guys Im installing my smc trunk mounted injection system and I was wondering where the best place to run the line into the engine bay is. The whole around the clutch pedal Is already filled with wires for my amps and guages. Should I just drill another whole, or is there another spot thats easier and doesnt require to be drilled? Thanks for any help.

Try the rubber grommet on the passenger side of the car. The main harness comes out from there. If you do happen to come out there be sure to wrap it in a heat shield of some sort and secure it away from the turbo.

Its stainless tubing so heat shouldn't really matter.

even if its stainless you have to worry about the rubber seals at the ends melting.

Hmm are there any other grommets I could use then?

Take off your top mount, just under the pitch stop there are a few grommets. Take a really long screw driver and push it through down and towards the drivers seat. Should be able to get to it under the dash at that point to tape your hose to and pull it back through.
