kto434 108 #1 Posted May 27, 2017 Has anyone added an oil pressure gauge to their 416-8, P216 Onan-powered tractor? If so, how did you do it. Also, is it possible to add a tachometer to a Onan P216 with the same hook up as a P220? Thanks. 1 Share this post Link to post Share on other sites
cleat 4,895 #2 Posted May 27, 2017 I would think that you would just replace the idiot light switch by the oil filter with the gauge sending unit or just hook up there if using a mechanical gauge. Tach hooks up the same, I have a 16 HP engine in one of my 520's and the tach works fine. 1 Share this post Link to post Share on other sites
