JamesL2 - 3/26/2025 05:32 Hi I would like to add a oil pressure gauge and fuel pressure gauge to this combine. Is there a gauge to monitor my engine air filter being plugged? I clean it everyday...but sometimes it gets forgotten. Where would I get these gauges? Anything else I should add? Looked back a posts...in 2013, daa and jalopy talked about digital and the site duallymax suggested to purchase from isn't avaliable
