Espar Heater Progress Almost Complete

Installing the Espar D2 Gen 3 Diesel Heater progress. Heater is secured with new fuel pump location. Exhaust and intake are connected but exhaust is not secured yet until I install some heat shields and then install the Syncro Diesel Skid Plate. Heater is fully functional, but now, I need to make sure the exhaust will NOT be melting anything... This Time.
