Fuel filter opinion?
 

Gentlemen:

I've seen about a fifty/fifty mix of cubs that had fuel filters (vs) no fuel filter. The 1650 i'm working on now does not have an inline filter (it might have been removed) before i got it...yet my 125 had one in place when i bought it. Any opinions? Thanks

Put one on it. It's cheap insurance against carb problems from dirt getting in it. Mine has a sediment bowl and a filter.

i would say its personal preference. me, I would put one in just for peace of mind, but I am also anal about things being protected

Not sure about the QL's but the wide frames have a screen on the topside of the fuel shut-off. Protect your carb with something.

The IH built Cubs did NOT have a fuel filter on them. They either had a sediment bowl or a screen at the shut off valve.

I have added fuel filters to all my Cubs for the same reasons as mentioned above.

I have been thinking about putting a filter on. When we got the cub the tank looked like it hada lot of sand in it. There is a screen in our tank (on a 1250) but I would still go with a filter.
Its around a 30 year old screen, so I'm sure at some point it could get a hole in it and allow something through.
And on top of that you have the same number of years of dirt in the tank.

I pulled the tank off and rinised it out with a lot of water (plastic tank luckly so I didn't have to worry about the water), and then I waited a week so all of the water would try. You could throw on alchol in there or some other stuff and clean the water out, but I prefered just to wait for the water to dry on its own.

My only cncern is this is a gravity feed system, which have a lower tolerance to filters (meaning some filters could be too good and slow the flow of gas also). I heard about this more with some older B&S eginens, without a B&S filter. I don't know how this is for the Kohler engines most of us have.

With this I just don't know which filter to get, if it even matters.

I put a filter on mine and the fuel would not flow through it. It's gravity feed, and the tank on my 122 sits on top of the engine. If someone has a P/N or Mfgr for a good filter that will flow with about 4 to 6" of gravity drop, I'd be glad to listen.

On my cubs that originally came equipped with sediment bowls, I disassemble them, thouroughly clean them, and re-assemble at least once a year. Its very simple to do, and in my opinion if all is kosher in the sediment bowl, and the tank is clean, a filter is not required.

On my newer cubs like my 82 series, they relied upon the screen in the pickup tube to filter contaminants, but like many have said this can clog up or get holes in it, etc..I always ad a high flow filter to these ones.

By hi flow, I mean there is simply a brass screen inside of the filter, similar to a sediment bowl, and you can easily see through it while peering in either end. I picked up a bunch of these from my local IH dealer several years ago (they are red in color..pancake style)
