Hydro Hot filter change

[jerry davis]

Finally getting around to changing the diesel fuel filter for the Hydro Hot unit which is mounted on my drivers side wheel well inside the propane compartment.

Since the poly portion of the existing filter must be removed and installed on the new filter it's not just a quick on off job and I'm concerned that I will have fuel everywhere as there is no way to turn off the fuel in front of the filter. The line doesn't look crimp-able.

If I wait until the tank is down below half would it then be an easier job or does it make any difference.

Anyone else done this seemingly simple job?

The pro's take a large zip-lock bag, place it around the filter, spin it off into the bag. They have a rag & the new setup to go on at the ready. I watched mine done (I have a spin-on type filter) and it didn't drip much. Very sanitary job w/the bag method.
Then use the fuel from the old filter to start your coals for a coupla fat steaks. Or maybe pour it into your old motor oil before disposing (if you have a propane grill).

If you have the spin on filter, make sure you also replace the O-ring on the threaded shaft before you put the new filter on. If you have the type with the sight guage, then I have not done one of those, but it's a water fuel sperator type, and again, it should just spin off/on.

To prevent the fuel to flow, you can get some hose clamp off pliers at NAPA auto parts I have been told. I am going to get two pair of each size, so I can also crimp off radiator hoses if necessary. In a pinch (no pum intended), taking some needle nose vice grip pliers and putting small vinal hose over the jaws to protect the surface you are going to crimp off should also work, be careful, it seems WRV used plastic fuel lines on the HH install, and I don't know the life expectancy of this material.
