Davco Fuel Processor

The Davco fuel filter system does not cool the fuel, It does have a optional fuel heating system to prevent jelling of fuel in cold climates.

It seems like cooling the fuel would be counterproductive in the temperatures here.

The price for a Davco appears to be around $200. For this amount of money I can get approximately 100,000 miles purchasing the Cummins recommended filters and then changing them both once a year (4 years of use). There is no need for me to get dirty, smelly or pay some one to install the Davco in place of my factory installed Cummins preferred primary filter. I will stick with the system Cummins is comfortable with. I might be interested in a Davco if I was running 100,000 plus miles a year. On an RV I just do not see the return on investment.

I have a Davco 382 that I installed in the place of the primary fuel filter. One of the best upgrades that I have. No guesswork on when to and when not to change the fuel filter and has a check valve to prevent fuel from running back to tank when changing also easy to prime without contaminating fuel. I use a 7 micron in the Davco primary and a 2 micron in the Caterpillar secondary.
