Hi ,pump needs to be isolated if fixed to chassis as much as poss . I used the rubber hangers similar to what the exhaust guys use to hang mufflers with . Thats prob the best you can do .Can`t hear it inside the c/van as the diesel heater makes a mind blowing amount of noise anyway ,compared with a previous gas heater we had . Cheers .
Mine certainly does not make a "mind blowing amount of noise". On startup, the speed ramps up and it does get pretty noisy, mainly outside. But inside, after 2-3 minutes it is much quieter than a fan heater. I also have a second muffler ready to push on if I am worried about annoying the neighbours. That makes quite a difference.
It pumps out so much heat I can't imagine I would ever want to run it on high for very long.
As for the ticking pump, I have wrapped mine in sound insulation material (Jaycar), and mounted it with cable ties holding it against a piece of cushion foam. Mounted in the front boot it is audible inside, but not a nuisance. The next step is to feed the pressure side fuel line inside some soft rubber tubing so it can't drum on the body.

Soft mount (even suspend ) the pump and put a loop in both inlet and outlet fuel lines before attaching to the pump to let the pump move a little instead of sending the vibration "down the line" . I have 2 diesel heaters (1 in Slide on and 1 in Van ) and apart from fan and pump noise for a minute or so on start up run quietly once up to temp. and settle down.
bowser... A bit more information regarding the location of the pump. whether it is inside the van or outside would be helpfull.. mine is located at the rear of the van outside and away from the sleeping area. suspended and wrapped..
