Ok, so some of us aren't so bright...

looking at the filter in the tank on top the sediment bowl, like you all said, it's open at the top and its only there to catch stuff drifting about at the bottom of the tank and keep it form sliding down into the sediment bulb.

OK. so where does the fuel get into the sediment bowl in the first place? via the brass tube that sticks up or through the filter and down around the brass tube? Or is the former 'normal operation' and the latter 'reserve'?

help us newbies figger it out.

thanks!
The main fuel, two turns open on valve, goes thru the long tupe into the bowl and the reserve goes into the bowl at the bottom of the long tube down inside the screen in tank.

isn't there a filter
attached to the
oil plug used to drain
the engine oil?
iowa
it looks like a steel mesh 'pop can' with the oil drain cap as the base of the 'pop can' with no top. Many have been lost over the years; its purpose is to prevent larger particles from getting up into and damaging the oil pump (then I think the oil goes to the filter, and onto the engine).

From the pump the oil goes to the oil galley and pressure relief valve. part of the oil from the brass fitting at the back of the engine goes to the filter and then to the gov housing. there is a good oil flow dia in fo-4.Only part of the oil is filtered. oil flows directly from the pump to the main and rod bearings with no filtering.
