I finally bought a fire system for my NA. I bought the E.S.S. 5 Liter AFFF SFI Fire System from saferacer and I'll be mounting it in the trunk. The bottle has 3 ports on it. My plan is one line to the engine compartment then split to each side of the engine and one line going to the driver towards my legs/feet. I'm shooting for the majority of it going on the driver. Can I just cap off the 3rd port? Any major flaws in my plan? TIA
