TJ5208 1,841 #1 Posted February 3, 2022 (edited) Can you buy rpm heat and oil pressure gauges for a 20 hp Onan? What all gauges can you buy? Edited February 3, 2022 by TJ Salyers 1 Share this post Link to post Share on other sites
kpinnc 14,630 #2 Posted February 3, 2022 (edited) Most any guage can be replaced. Just make sure it matches the sending unit for whatever you replace. Getting them out is another story. Easiest way is to remove the center console so as to allow the plastic cover to move up on the steering shaft enough to pull each one. It's a job...

kpinnc 14,630 #4 Posted February 3, 2022 Yeah I forgot the 520-8 doesn't have those already. In that case you'd need to be sure you also get senders for whatever guage you need and add them to the engine. 1 Share this post Link to post Share on other sites

kpinnc 14,630 #7 Posted February 3, 2022 I am working on a oil pressure guage setup now. We'll see how it turns out. Most any automotive guage with sender included can be made to work. The sender threads into the plug hole on the exterior of the oil pump, and the rest is electrical wiring. 2 Share this post Link to post Share on other sites
