12v 5.9 intermittent power drop and white smoke

[brokedown]

I added a 100 gallon treatment bottle of the Power Service treatment yesterday. The tank is gonna get a good cleaning soon!

I wonder if there is any merit to installing a marine "fuel polisher" in our buses that see intermittent use?

If you are filling with fresh fuel regularly it wouldn't have any benefit but for those that spend weeks/months parked at a time It may be of value.

I'd think it would be simpler to use a fuel additive annually then it would be to set up a constant filtration system like that.

About those Fuel filters. I'm just seeing the pics posted. Maybe i'm wrong but it almost looked like red alge more than rust. In person was it really rust??

I'd buy Several filters, after all they don't go bad. On the road you can fill one with any New motor oil when installing.

If so Immediately go to the drain plug on the tank and crack it loose and see what leaks out first. Fuel?? Water??

When mine is parked it is parked on Full tanks. This keeps the air in the tanks to a absolute minimum.

I've got the same 12V 5.9 in My 94 Ford. My rear filter has a drain plug on it. Every spring on first startup I crack that plug loose (with the engine running,
to see IF there is ANY water in the filter.

My filters looked different. More plugged I think - at least the first in line. This is from the separator.

So why are you filling it with motor oil and not diesel fuel?

I was wondering the same thing!
