Anyone have a problem getting the bulkhead fittings to seal up on a plastic fuel cell? I got my brand new Summit cell and can't get it to stop seeping. I've tried to tighten them up as best as I can, but no luck. Is there a good way get a wrench on the inside part of the fitting? I noticed in the instructions it says that a leak in this area is not a warranty item. I guess I should have waited for the Jaz cell that was backorderd, damn rain has cancelled all the races around here.
