you probably have let the RV sitting with less than a full tank of fuel on multiple occasions for long periods of time between races---you need some diesel fuel cleaner like bio kleen or something similar it will say algae/bacteria cleaner on the label--you don't need cetane boost or injector cleaner wrong stuff-- but algae/bacteria cleaner -your problem is you have some water in the fuel tank and the water breeds algae in the fuel tank---check the filters and run some stuff thru there for the next 2-3 tanks should help clear up the problem---also always try to keep the tank full between races this will help eliminate the problem too---FED 387
