Magnus Secondary Fuel Rail Weld in Kit



The Magnus Secondary rail kit has been produced for years as an optional addition for Magnus manifolds. This kit provides a quick economical way to mount a secondary set of fuel injectors to your existing manifold. No downtime in sending your manifold in for modification.

The unique one piece injector boss design also makes it very easy to line it up when welding, eliminating the possibility of accidentally welding one injector boss on crooked, or having crooked fuel rails, and/or badly sealing injectors.  This would flare up an extreme case of OCD with your fabricator, and cause him to whip out his angle grinder in anger and possibly ruin something while cutting it off to start over again.  Do it right ! buy this!

When you’re running E85, E98, Methanol or just making big power on gas, one injector per cylinder just doesn’t cut it. This is your solution!
