Have a 2007 EPA Maxxforce DT that is leaking fuel out of the primer button. Can this be fixed by itself or does the entire fuel filter header have to be changed?
Had the same problem not too long ago. You have to buy the whole filter housing. You just need the O-ring but they don't sell it separate. They got you by the short hairs.
We've bought 10 buses from them over the last 2 years, so they still have at least some bus sales still. At least we got Cummins instead of Maxxforce junk, though we've already had our fair share of issues with the red ones....
