I woke up this morning to a puddle of fuel in my garage under my bike. It turns out that when the bike is running, fuel leaks from under the fuel pump "cap," the part that screws onto the fuel tank, holding the fuel pump. Anybody else seen this? I believe the previous owner replaced the fuel pump, so possibly improper installation? Is there a sealant there that I need to apply or reapply? I suppose I need to pull it out and have a look; that's happening soon. I'd love to have advice from those that have trod this path before me. Many thanks.
