In line fuel filter?
I dunno. I've pretty much exhausted my knowledge of the thing.
It was only $99 about 5-6 years ago, so it may have outlived it's usefulness. There's a guy that does repairs, but I can't quite see spending $50-60 to get it fixed.
If I can't start it Saturday a.m., I'll pick up a new (yet similar) model and throw this one on Craigslist for $10.
