DownHome 40 #1 Posted March 15, 2016 Trouble shooting my 8hp k181 855 and I think I've narrowed it down to the fuel pump (vacuum style). What is the best approach? Can they be rebuilt? Is there a replacement that be purchased? I bought a new fuel pump for my 10hp k241 1054. Are they interchangeable? It has the mechanical arm. I feel like I'm so close to getting this baby working. Please help. Share this post Link to post Share on other sites

The vacuum style pumps can be rebuilt. Usually it's the diaphragm that goes bad. But there are also a couple of little disk type one-way valves inside that get gummed up. If they are okay, and all you need is a new diaphragm, contact member buckrancher, he sells a nice replacement. 1 Share this post Link to post Share on other sites

If I can't get a diaphragm can I swap the pump out for the other version with the arm? 7 minutes ago, rmaynard said: Share this post Link to post Share on other sites
953 nut 60,265 #5 Posted March 15, 2016 You could also consider putting an electric fuel pump on it, lots of threads on here about people doing this. Share this post Link to post Share on other sites

I ordered a new diaphragm from Brian (Buckrancher) but I need to use the tractor tomorrow so i picked up an electric fuel pump and installed it this evening and she fired right up! I'm so excited. I'm still not sure what I'll do long term, vacuum vs. electric? Regardless tomorrow once I change the oil and put on the new drive belt I plan on putting her to work. I have some gravel to level out. I'll post pictures if all goes well. 1 Share this post Link to post Share on other sites
rmaynard 16,348 #7 Posted March 18, 2016 Leave it with the electric one on. Save the new diaphragm for the next project. It never hurts to have a spare laying around. 2 Share this post Link to post Share on other sites
