How to quieten the diesel heater dosing fuel pump
I have recently installed the Planar diesel heater in my Hatteras 37 Convertible. it is an amazing heater, heats the big boat in 30 minutes from 45 to toasty 69 degrees. On my previous 36 ft sailboat i had an older Eberspacher (Espar) diesel heater and i remember the pump was noisy especially in the night when it is quiet and the heater kicks in. This time i screed its bracket onto a glassed in piece of plywood on the side of the hull in the engine room, but i have wrapped it in some 'duct seal' compound i bought at Home depot (on suggestion from another boater). it helped a little bit but i can still hear the pump ticking while working. Would suspending it in air without screwing into anything strong help to educe the noise?
