The manifold pressure firewall bulkhead fitting that Van's suppies did not mesh up with the Dynon sensor, which requires 1/4" tubing. I could have purchased another fitting that converted the smaller Van's tubing with the larger Dynon sensor fitting but I decided to just replace the firewall bulkhead fitting so I could use a single piece of 1/4" Tygon to connect the sensor to the firewall fitting.
