I have heard a lot of talk About heaths PMD Isolator and SSDiesel FSD Heat Sync. I dont want to sound like an idiot but are these the same two things but just different names cause they are made by different companies? or are they two completly different things? Thanks for the help.

I believe the SS Diesel one is a heat sink mounted to the side of the intake. The Heathe diesel one mounts outside the engine bay. But they both move the (PMD Pump mounted Driver) or the FSD (Fuel Solenoid Driver) off the injection pump. PMD and FSD are the same part, just different name. They say heat is what damages them. I went with the Heath one just because if the heat is what kills them when you shut the engine off on a 100 degree Sacramento, CA day the underhood temp is probably close to 200. I thnk Kennedy diesel sells one like SS also.

Go heath, the other heat syncs still stay under the hood and will still fry up and fail. My heat sync cooked my PMD in a year, until I shelled out the high dollaz for the heath iso.3 year warranty.

I think Heath's is a 7 year warranty isn't it?

When the Fuel Solenoid Driver is mounted on the Inj Pump, it becomes the Pump Mounted Driver.

If a PMD is removed from the IP it again becomes the FSD.

When the FSD\PMD is sold on one particular site, it becomes the Pretty Dumb Moniker, PDM for mounting on a heat sync - sync, as we all know, is short for synchronize.

Doannever let yer family ride in a vehicle, without wunna them, eh?

Us cool dudes prefer to mount the FSD on a heat sink, for maximum thermal transfer and radiation, preferably outside the hot engine bay in the cool, cool ambients of the local Baro.

Hope this is helpful to ya, rig.

yeah, either buy the kit, and make something up yourself. Whichever you do, just make sure it ends up out of the engine bay.
