I installed a Monitor KHW demand water heater in 1993. It burns kerosene which is stored outside. The water heater was discontinued by Monitor a year or two after I bought it. Replacement parts other than the nozzle and electrodes are unobtainium. It's a complex thing and even though I'm licensed to service and install oil fired appliances I never dared to get too involved with this water heater. I purchased a Toyotomi on demand water heater 5 years ago when this Monitor started acting up with the delayed ignition but have it stored as I see how long the Monitor will last. The outside fuel storage tank float gauge broke and allowed a little rain water to enter the fuel tank. Coincidentally or not the heater started having worse delayed ignition (fuel is sprayed into the chamber but doesn't light off for a few seconds - resulting in a loud boom and smoky light off). New nozzles and cleaning electrodes didn't help for long. I poured 1/2 a cup of Performance Formula into the fuel filter bowl and there's been no delayed ignition ever since (about 3 weeks now). One possibility is that the concentrated Stanadyne dose cleaned the fuel system (100 psi pump, lines, valves, nozzle) or it dispersed the water into smaller particles which allows for better ignition.
I've used Stanadyne in the '93 7.3 for 25 years and also use it in other diesel equipment and never have any water to drain from fuel sumps/filters.
I have no financial connection with Stanadyne but felt that what this one time treatment did to correct ignition problems with the water heater is applicable to its use in diesel fuel systems.
