Generac 7500 Fuel filter replacing.

Hi.

Iím about the go on my first rodeo replacing fuel filter and oil, oil filter for Generac 7500 on a 2005 Alfa see ya gold. So I plan to change the oil. Then change the fuel filter, top the new filter then installing.

Iíve heard about priming the gen so air wonít get in and cause it not to start or other fuel issues. Is this priming process done with just pressing the prime button or itís actually involved other stuff like disconnecting fuel line etcÖ?

Thank you for your tips.

I worked fast and still got fuel leaking down my arm. I am guessing it would be better to clamp off the incoming line, other than that no real issues. Be very careful about the fittings as working in that tight space they can be cross threaded easily.

Priming is real easy, just push the start switch a few times without letting it crank and then start her.

There was also an inline fuel strainer in mine on drivers side under cover. Is yours on slide. If you open covers inspect the exhaust flex pipe for cracks near manifold. Mine cracked and was plugging radiator with soot.

I know some model has prime and start on the same button (press down and hold to crank). On mine itís 2 separate buttons . I have the prime button and start button. Are you suggesting I should just hit the prime button and not the start button? Cuz mine as soon as you hit the start button after prime it will start cranking.

Thank you for your tips folks. I did it and it ran fine after starting with no load and then with AC on for 30 mins. Hopefully it will stay that way.
