mounted fuel pump on bottom of angle bracket. The fuel pump on an Espar heater is incased in a rubber mount and is pretty quiet unlike some of the other heaters on the market that have noisy fuel pumps. Hole for heat outlet going into box under where my feet reside when I am at the helm. Swivel outlet lets heat be directed any desired angle as it spins 360 degrees. Note plate heater is bolted to,see the pipe below that plate which is the combustion exhaust with a drain that will go to the newly installed thru hull
