Newbye ??? Fuel filter n water drain

[ar15bang]

Hello, I am new to diesels and have this Question.

I have a 99 F350 and it started to run rough, changed the fuel filter and it helped, then was told to drain the water from separator with yellow lever. Drove it for 15 min. but it still not like before. Drain separator again and there seem to be fluid still draining. ???is it normal to accumulate water so quickly? how often should I drain the water?

Truck was running perfect until it sat for about two weeks, subject to mostly short trips.

Thanks, Alex

that is not normal. i never seem to have a water issue. did you drain teh fuel bowl before you put the new filter in?

when does it run rough? all the time?

I drained it afterwards, was I supposed to do it before hand?

Always run like a champ.

It has gotten better with the new filter, I am thinking of filling it up with "new" diesel and using an additive. Maybe I got an old load of gas, last time I filled up.

yes, before, so the dirty fuel doesnt get behind the filter. next time fill the bowl with some seafoam when you change the filter. then run the truck for a few mins or half mile or so then let it sit overnight. clean out the injectors, then drive off the next day. ive heard good results.
