I connected the manifold pressure lines from the engine to the ACS2002 engine monitor and the Lightspeed Electronic Ignition control box. The three sources use different size tubing; the firewall fitting uses 3/32", the ACS 2002 uses 1/4" and the Lightspeed uses 1/8". I tied these together using a T fitting and a reduction fitting. I manufactured a support "hat", rivited it to the cockpit side of the firewall and used plastic ties to secure the fittings and line.
