Re: RV broke down
 

The algae is caused by several sources mainly condensation in the tank diesel only stays good maybe 6 months not like over a year for the old type fuels--next because those engines are injected when the warm /hot fuel is bypassed back to the tank and it hits the cooler fuel or surfaces in the tank condensation occurs ---over time this allows the algae to develop and build up---google it and read up on it you will get a real good education about what is going on in your system--- the other thing is if your RV is an "older" unit this preventative maintenance most likely has not been done by the previous owners/s so its just a matter of time before this is the result you are going to get---2-3 treatments over a period of time should help the situation--- don't go crazy and go putting lots of additive in the tank cuz if you could look into the tank the bottom of the tank probably has a layer of black tar looking "crud" or a gel like substance that is the result of the algae process---look at the fuel going into the engine it should look clear and light colored not dark which is an indication of "contaminated" fuel---FED 387
