Thanks for the reply. I have attached a photo of the metal fitting from the engine block connecting point connecting to a flexible hose that connects with the plastic tubing from the fuel tank. (Is the metal fitting broken off from a bolt?) Part of the problem is I don’t know what I am searching for at the crankcase. Having searched for a connecting point, I am at a loss. It must be obvious, but I can’t locate the fitting. I am assuming it is above the oil pan, and at the front, driver’s side of the engine block. Hoping this description makes sense😊. Thanks again for any help!
