Can i use a low presure small engine pulse system on my 22 engine to get fuel to go thru a filter ?
Thank You --lorenzo

There is an alternative to a filter which will do what you really want, but didn't ask for. With that in mind, and relatively certain that you are intent on having a pump, here is something to chew on: viewtopic.php?t=3167

The question arises as to why you need a filter? If it is to filter out rubbish in the fuel system, pressurising the fuel to push it through a pile of rubbish is really not the answer.

i do not want to push junk ,just to filter the gas so it does not get to the carb. [[the set up -- from the tank to a filter to a pump and then to the carburator]]] the tank is not too far gone just to be on the safe side
just wondering if anyone has used a pulse pump and any luck with it .thank u Lorenzo

Whats wrong with the filter in your sediment bulb?

When I had my Chevrolet overhead installed I had to use a downdraft carb so needed a pump because of under seat tank.
Not sure what pump you are thinking about, but the Carter 6 volt pump I used ran all the time and was a pretty good draw on the battery/generator. Even the so called low pressure pumps put out more then the Ford stock or aftermarket carburetors can handle or need so then you need a regulator. If you must run an extra filter, one of the gravity feed lawn mower types should be fine (just keep it away form the exhaust pipe), but if there is so much crud in the tank that an extra filter is needed, pump or gravity, you can still end up by the side of the road when something plugs up.
Don't forget there are two flushing drains on the T, at the tank and carburetor.

you have asked twice about pulse pumps. I have already supplied a link that has a good discussion on that. Have you read it???

If you're after a pump that's one thing however if it's just filtering you want go to a mower shop and get an in-line filter for a gravity fed system. Most riding mowers are gravity fuel fed. I have used this type of filter for quite a while with no problems.

I looked into using a lawn mower filter. The labeling mentioned "for horsepower xx" or "with fuel pump" both looked like the attached photo of the red one. Then I looked into K&N having one of the best reputation for filters and saw a similar one that indicated a high flow rate. The price difference $4 vs $10. Both have the same screen surface area as the brass screen in the sediment bulb but may have a difference in screen mesh size. The K&N is clear so one can see inside.

Two comments - FWIW almost all John Deere lawn tractors have a small vacuum-operated pump for the fuel. It is common for the fuel level to be below the carburetor float bowl.
Second, it has been my experience that the screen in the sediment bowl will plug up before the carburetor cruds up. Ask me how I know.

It won't hurt to use one of these. No pump needed. If your tank has enough crud to overwhelm this, you need to fix or replace the tank.

Scot I deid read it,- Steve jeff i think this is the best option for me
Thank you all for the great info Lorenzo

Take the pump and filter off and clean your tank thoroughly. You won't have any more trouble after that.

Band-Aid vs. fixing the problem- I love these debates!

New-comers posting honest questions may or may not learn anything about their problem, but they no doubt leave having learned something about the posters.

They have larger in-line filters than the ones you pictured. They are for smaller engines. As for those in tank screens: you can't get 'em out easily. Pass on that as far as I'm concerned.

Correct about the red one and similar red ones are for lawn mowers and low HP engines. The K&N filter shown above per K&N "The K&N 81-0241 In-Line Gas Filter is perfect for racing applications and can be used with a variety of oils and fuels including methanol. The 81-0241 stainless mesh in-line fuel filter has a flange diameter of 5/16 inches. It comes with a 1.55 inch body diameter by 1-3/4 inch overall length"
