Generator: Changed engine oil and filter. Added 2 qts 15w-40 Rotella. Old oil filter was barely hand tight. Changed air filter and tank to pump fuel filter. Changed fuel line from filter to pump. Was 5/16" but replaced with 3/8". Tank to filter line is brittle so Future Jess should replace filter to BF840-K1 (5/16") if she doesn't want a major job dropping the generator to change the rest of the line.
