fuel

I am reaching out to you all to get some ideas. About a month ago, 3 of my gauges started acting weird so I thought it might be a bad ground issue to my panel. My PSI Gauge, Fuel Gauge and Volt gauge we're screwed up on the same trip. My RPM and other gauges worked fine. Fuel shows empty even...

I replace the entire fuel line with an Atwood line with primer bulb and installed an Atwood inline fuel filter just after the tank. The bulb will not get firm and the filter doesn't completely fill. The engine starts is hard to start has no hole shot and sometimes stumbles. Ideas?
