I have a John Deere LT133. It fits perfectly on my lawn mower. But it didn't work at all. I even feel the diaphragm like other people have said. After spinning the diaphragm, a small amount of gas passed through my filter, but not nearly what would be needed to start my lawn mower. This item went straight to my trash. Thanks for wasting my time on the unnecessary part.

I was excited about the price of this product but should have known I was going to have problems with it. Installed, engine cranked, but petrol does not pump. I could hear air escaping somewhere so I took it off to diagnose the problem. I immediately realized that he had a bad seal. Fuel was ejected directly into the crankcase by the drive lever.

I bought this pump because the part number matched another website which said it would fit my mower. As it turned out, the pump drive wasn't exactly the right shape for the CH12.5S. The pump broke very easily and I was able to continue using the drive from the old pump. While this could have voided the warranty (that prince, who cares), my lawn mower was back up and running in no time.

Love the price! Ease of installation. Cannot find an OEM product. yes it is plastic So don't let him run out of gas. Works well! I found I was losing 1/4 tank of fuel pressure. So I'll just stock up beforehand. If you run out of fuel, you increase the likelihood of damaging internal parts. I recommend and love that they include an extra fuel line, built in filter and fittings.

Diaphragm pusher has come loose where it goes through the diaphragm. After standing overnight, he refueled the engine with gasoline. I'm a truck and heavy equipment mechanic. I disassembled it to investigate the problem. Very bad production. It cost me about 10.00 for an oil change, labor and a trip to the UPS store to return it. How many defective ones did they build? I am looking for another supplier. Through Simplicity it costs 184.00!

Pump fittings have never been the way they were. There was no check valve in there. Only one 1/4" fitting is listed, but two are required, one for the inside and one for the outside. I would return it but I have to cut the grass. So I used a diaphragm, fitting and gaskets from a new one I ordered and rebuilt my old one. Remove to save two hours of trouble, really look at the details. Or just order a diaphragm and gaskets for a few bucks.
