Recommend Methanol Injection Tubing

epiphanyray · 10-15-2017, 10:39 PM

Guys, my tubing for my meth kit appears to be that silicone transparent type. I really want to replace it for safety. Can someone recommend good tubing? What do you all use?

I would think a braided stainless, rated for fuel, would be your best bet.

No experience with meth so I cannot personally recommend a brand. Subing though.

The standard polyurethane (?) meth lines are fine as long as you use compression fittings AND don't expose them to too much heat (wrap them in areas near the turbo).

The next level of upgrade is braided stainless (like Earls) that can withstand any type of fuel and/or pressure. These will have to be custom made (for length). Note that the meth pumps don't support these lines, so there will be a transition. I have only seen issues with meth lines becoming frail inside the engine compartment (where it is also dangerous).

Contact Raza @ RK Autowerks. He's got upgraded meth lines along with the fittings.
