I changed the oil, filter and fuel filter. This time I drained the fuel out of the filter housing before unscrewing the bottom instead of dumping a pint of diesel all over everything. My 3725 has the clear plastic bowl filter housing that has the manual priming pump on it. I also figured out that the air bleed is the 12mm bolt right behind the priming pump that has a screwdriver slot in it. It needs to be unscrewed quite a ways to open but it eventually does. The drain on the bowl won't work unless the air bleed is open, and even then it's really slow. I think it's mostly for removing water in the bowl.
Leaving the air bleed open and turning the key on to get the lift pump going worked well to bleed the air out of the housing. I didn't even need the manual pump.
The filter was pretty gunky with what looks like tiny bits of that dark red algae stuff. I have had a problem with that growing in my gas cans so I'm not surprised. I use biocide but it still grows. I've taken to cleaning the cans out with soap and water if there's any of that stuff in there, before I fill them up again.
Hopefully the stuff in the fuel tank is just remnants from the cans not new growth.
