Dual fuel filters

The forum only designates "gasoline" engines, but this may apply anyway. I did routine maintenance the other day on my Kubota ZD21, lubricating everything and changing oil, filters, etc. Although I changed the fuel filter it was still bogging down in a pull with the blades engaged. I ordered a fuel pump thinking it was getting weak. When I got under it to change the pump I discovered a second fuel filter. I decided to change it first. Once it was changed out I decided to cut it open. It was almost totally occluded with crap. What a difference good fuel flow makes

Although no real question, I just wanted everyone to be aware there may be a second filter on your machine, so don't ignore it.

The battery on my excavator died last week. Only after removing the seat to get at the battery did I find the hidden hydraulic filter. It really amazes me why filters are hidden. Second to hidden filters are ones located so when changing them they drip or drain onto electrical connections or hot engine parts that could cause a fire.

In many cases items are designed to facilitate the manufacturing process (assembly line efficiency and low cost) as opposed to the after market maintenance process. This is especially true for consumer products and cars. They are not designed for the homeowner to fix or maintain but rather for the professional to repair at a high cost. Much of that high cost is related to removing items not necessarily related to the problem part but needed to be removed just to get to problem part. And often time a special tool is needed to disassemble an item.

I remember, specifically, the #8 spark plug on the 1966 Chevy Nova. Had to loosen the motor mounts, lift the engine 6" just to gain access to it.
During tuneups it was quite often ignored. During such a tune up, I remember pulling an AC Delco spark plug from #8 while the remaining 7 had Autolite's.

Was it the chevy monza [?] that had a V8 that required pulling the engine to tune it up ....... or cut access holes in the wheel wells
