I have comprehensively renewed the emissions systems in my old (1973) Dodge pickup, acting out a sense of social responsibility actually. This time was the very beginning of comprehensive emissions systems in America, though a tiny beginning was made in 1964 with the requirement for PCV valves - which were, by the way, good for the engine as well as the atmosphere as compared to the "road draft tubes" which they supplanted. From that time forward tiny incremental changes, not only in emissions amelioration, but in crash safety and control rationalization as well took place every year, with 1968 being a landmark date, with the institution of comprehensive, though yet modest, federal requirements. The result of this was seen in headrests, shoulder-belts, locking steering columns, and so forth - things that didn't exist before that. The early '70s began to see substantial changes in these areas, and led immediately to drastically lowered compression ratios in engines - to allow "low-lead" and then "lead-free" gasoline - across the board, "safety-bumpers", etc., etc. And ever more complex and intrusive emissions systems. Jimmy Carter is often considered a poor, or even failed president, but in this area he shepherded through congress one of the most important legislative mandates ever, which very literally led directly to one of the most thorough and extensive changes in human society of all time. This was the CAFE act (corporate average fuel economy), and was prompted as a response to the first "gas crisis", which of course utterly changed the entire dynamic of economic and political power - to America's confused detriment. The point at hand is that the twinned new requirements in both fuel economy and emissions control were literally impossible to meet with any existing technology. Carter gambled, so as to speak, that this law would literally force Detroit to invent solutions to meet this impossible task. And they did. This was to computerize cars, and it worked well. New cars have power, economy and drivability that were simply undreamed of. Of course it added complexity, weight, and cost largely, but that was the price to be paid. And not incidentally, cars are much safer in the bargain. But yet, to return to my point, in the early '70s this was still a few years in the future, and the mechanical emissions systems, largely vacuum, temperature, time, and engine speed controlled. were plainly lousy. Power, economy and drivability all suffered badly. I personally was tasked with decisions on several levels - legality, social decency, cost, practicality, and results - regarding what to do with this archaic and feebly effective composite system, which was very literally was a series of sloppy and nasty add-ons to an existing engine, as I renewed the powerplant in my old truck. In the event, I decided to keep as much of this equipment as seemed practical. There is in fact no real-world enforcement mechanism in place for the old-timers - I believe it's thought that there are too few of them, and they are driven too few miles, to be significant - and I agree this view. So it all came down to decent social behavior - and that's real to me. So I indeed renewed my in place emissions systems - there were several, and I fettled them all. The one that I'm going to explain was the ECS (evaporative control system). The need arose from the fact that liquid gasoline gasses off gasoline vapors at ordinary atmospheric pressure and temperature. This gasoline vapor, exposed to sunlight, was a substantial contributing element to photochemical pollution - smog. Liquid gasoline typically was found in two places in a vehicle - in the gas tank, and in the carburetor float bowl. Both were simply vented to the air, where they were indeed pollutants - and they stunk up your garage! The solution, which in much modified form is still in use (no car even has a carburetor any longer), was to vent both of these sources - the gas tank and the float bowl - into a container, and otherwise seal the tank and the float bowl. The evaporative canister that received these vapors was filled with charcoal, which absorbed them. These charcoal incarcerated vapors were then periodically "purged" from the tank by a purge valve in the carburetor, and burned in the engine. Thus, no emissions, no stink, and the formerly wasted gasoline was now burned. It's a good system, it works well, requires little maintenance, and in no way deteriorates drivability - and increases your gas mileage! So, I completely rebuilt the whole system, and replaced the filter which filters the air entering the canister in order to replace the amount of vapor which is purged (the dealer still supplies them, though I had to buy six at once). But, there's an inherent problematic possibility. Like anything, the charcoal isn't immortal, and will eventually break down. When that happens, the charcoal dust which results can be drawn into the carburetor, and thence into the engine, by the vacuum which the purge valve employs to pull the gasoline vapor into the carburetor. This is bad news for engine, and is simply unacceptable. The answer is to put a small fuel filter (such as I bought - I don't even know what it's application is - a lawn-mower or some-such I suppose) to catch the charcoal, and you make it a plastic or glass filter so you can look for the (black) charcoal residue in the filter, and you then know it's time to replace the charcoal. Of course it's a generally bad idea to use a plastic fuel filter, as opposed to a metal-cased one, because it would certainly melt in an engine fire, and thus add to the conflagration. I strove to mitigate this liability by putting the filter adjacent to the charcoal canister , which is located in as remote as possible corner of my very spacious engine compartment (of course, my truck is a pickup - in a sedan, the canister would be located in the trunk). In the event, it all seems to work perfectly, and I'm all set for another 40 years of vapor-free driving. And the filter only cost $3.22 - thank you Amazon!

Works great, I will be ordering 2 more later. Thanks

Fit my John Deere E100 mower perfectly!

It’s just a cheap fuel filter that fits my lawnmower. I change it every year. Nothing special but affordable and it fits

works well. filters fuel like it should. 1023e john deere.

It works no problems

I have no qualms whatsoever regarding buying so-called off-brand parts, for at least two reasons: 1) It promotes price competition, especially versus the OEM guys. And 2) Someone other than the original manufacturer of your mower, tractor, tiller, or whatever may have outsourced the contract for the same part you are replacing. Example: My zero-turn mower manufacturer is insistent on the owner using only its brand of hydraulic filter. The manufacturer is big on displaying the US flag in its ads, by the way. Very patriotic. When I bought the manufacturer-branded filter, it had been shipped to the dealer with no protection....no celo-wrap, no box, no nothing. And to my amazement, this very pro-American, Wisconsin-based manufacturer had outsourced the filter to some shop in India. Make no mistake, the problem is not with the shop in India, but rather with the orange mower manufacturer not specifying a level of quality and protection for the shipment of the filter. By contrast, my Stens fuel filter was shipped with excellent protection and is superbly made. And you can be sure, when the moment arrives to replace the hydraulic filter, I'll likely pop for the Stens can. Same specs. Correct fitment. Price competitive. And properly protected.

it seems to be doing it's job but it's very very small, about half the size of the part it's said to be a replacement for. The plastic it's made from feels kind of thin/cheap as well, so I'll have to see how it holds up.

Great replacement part. Worked perfectly. Easy to install if you know how. Don't forget to clamp the lines or gas will go everywhere.

Top und schnell

Works no more bogging down due to fuel starvation

I placed the blame on the maker of this product for not receiving it for a long time. This was not a fair criticism. The fault was that of the postal service who I understand was overloaded due to the pandemic. I apologize to ISE for my comments. I did get the product and it works very well and I will order it again

Works as expected it would.
