gapper 22 #1 Posted June 3, 2018 Hello all, I have a K341S Spec 71223a. Is there a fuel pump rebuild kit for my motor? If not can someone help me with the part number of the fuel pump i need? I see so many different numbers for pumps saying they are for a K341. I would prefer to have my OEM metal pump. I am open to doing the electric pump but it would have to be a simple setup. No regulator needed. I found a old post on here that had a electric pump part number but i could not find that part. Any help would be great as i don't want to mount the fuel tank on top of the hood so gravity can do the work. LOL here is a couple pics of my fuel pump Share this post Link to post Share on other sites

Stealth126 54 #3 Posted June 3, 2018 I revived my original metal pump with a rebuild kit from then and now. More expensive than a plastic one, but get to stay original. Your metal is probably warped though and the gaskets they provide are thin. Share this post Link to post Share on other sites

I haven't taken a fuel pump apart so I'm not familiar with how the castings are shaped once disassembled. Can the casting halves be careful he sanded such as a cylinder head can? Or is there a commercially available sealant that will work okay with gasoline long-term? Share this post Link to post Share on other sites

You have to enter the new number to get a result. A Stens replacement here https://www.rcpw.com/search/?quest=a-236205s Garry Share this post Link to post Share on other sites

Stick with a new diaphragm as it's purpose is 2-fold, part of the pump, and a gasket. With the two halves trued and a new diaphragm, there should be no leakage. 1 Share this post Link to post Share on other sites
gapper 22 #7 Posted June 4, 2018 Thank you all for the help. I will be pulling my pump apart and checking the halves and to figure out the right kit from then-now auto. I will try to rebuild my OEM before going to a plastic. worst comes to worse I will look funny driving around with the fuel tank on top of the hood.

rjg854 10,708 #8 Posted June 4, 2018 I just took my fuel pump apart, off a 16 auto. It was leaking gas between the two halves. One of the screws was stripped out, which I replaced with a nut and bolt. The diaphragm was still usable but has some damage. The only problem I had was, it leaks oil between the pump and the engine once you shut it down. Now I know why they had 2 gaskets on it. So it's very doable, but before you read how to rebuild it in the kohler engine manual, there's some good tips in there. Share this post Link to post Share on other sites
gapper 22 #9 Posted June 6, 2018 I pulled the pump off and after a good clean job found that the four screws that hold the halves together were loose. I tightened them and reinstalled the pump to see if this was my problem all along. The pump is working and no more gas leak. I am going to run it for awhile to see how it holds up. Now i just need to figure out the kohler part number for the air cleaner and pre filter. The filter that is on it is Aprox. 6" OD 4 5/8" ID 3" H Does anyone have the Kohler part number for a filter of this size? Thanks for all the help Share this post Link to post Share on other sites

Mike-Casella 7 #12 Posted June 9, 2018 My apologies for being absent for so long. I just finished uploading a "how-to" video on rebuilding one of these 4 screw pumps, along with a few other miscellaneous pumps, using one of our kits. Rather than post the link to the video in this thread where it might get lost, I'll start a new one and maybe somehow it can be made to stay visible. Share this post Link to post Share on other sites
