Jose 11 #1 Posted April 17, 2023 (edited) Hey y’all, where’s the best place I could find a fuel pump for 520H Onan 20hp Edited April 17, 2023 by Jose Share this post Link to post Share on other sites
davem1111 2,030 #2 Posted April 17, 2023 I don't know the answer to your specific question, but personally I have replaced a failed Onan 16hp fuel pump with an aftermarket 12v pump and am quite happy with it. I don't like relying on these stock diaphragm pumps. If you want a stock pump, maybe chek out the Vendor section in this forum. 2 Share this post Link to post Share on other sites
cleat 5,934 #3 Posted April 18, 2023 I have a couple of my 520's now running the cheap $15.00 Chinese replica's (that I bought on ebay) and they seem to work just fine. 2 Share this post Link to post Share on other sites
