External Fuel Filter on a Duraforce

[Phototone]

I forgot about the filter in the carb on the high speed jet/nozzle, I wonder how many micron that screen is. Believe it or not I don't have a cellphone, but I found that there's a website pure-gas.org that will do the same thing. I was surprised to see that there are only 2 stations that are local for me (but not as convenient as the BP down the street) and both are marine stations. Does that mean that all the other gas sold elsewhere has ethanol in it?

More or less, YES, if it isn't listed on the Pure Gas website, it contains ethanol. If I were you, I would get a 5-gal. container and get enough for a few months. Without ethanol the gas lasts much longer in good condition. As you may know a great percentage of outboard motors are 2-cycle (or used to be), and smaller than car engines. These smaller engines (and this includes motorcycles) benefit greatly from non-ethanol fuel.

I wouldn't be able to use 5-gallons in a season, would it still be good the following season? The 2-gallon fuel mix I'm using right now I bought in May, yeah I know it's no longer fresh but I don't really have anything else I can do with it and it still starts on the 1st or 2nd pull (when I can get it to start and I'm hoping the shut-off valve will eliminate that problem).

No it just means they know that those station do not have it in one of the grades of gas they sale. Most BP's 91 or 93 does not have it.

In Michigan they don't require labeling at the pump and I wish they did.

I install a in line fuel filter on all my gas engines with a fuel line. I replace the all filters once a year, air and fuel. New filters are very cheap insurance and very easy job to replace.

The fuel line on a Duraforce is only about 6" long (if even that long), so your options are either a fuel shutoff OR a filter (unless somebody makes a unit that's both). Being there are two filters already, I'd go with the shutoff.

That is absolutely not true. No BP in Springfield Mo has ethanol in the 91 or 93 octane. It is not listed on that site. Not everything on the internet is true.
If you want your gas to last a long time put fuel stabilizer in it.

I guess you have me confused. You are saying it has two fuel filters already? Yes I agree it sure doesn't need a third. I guess its not for everybody but I just like a fuel filter that I can replace yearly.

The Duraforce engines have a non-replaceable 75 micron filter built into the fuel tank and there is also a replaceable filter in the carb on the high speed jet/nozzle.

Some people choose to leave off the internal carb filter (over main jet nozzle inside float bowl), and add an inline filter, so that if anything gets by the in-tank filter the inline filter will catch it and that is easy to change.

Otherwise you would need to take off the whole carb to access the float bowl to clean the carb internal filter. So it can make servicing easier if you set up the filters this way.
