Yes..Many times....I would start with your fuel pump and make sure the rubber hose is still connected (clamped) to it...chances are your rubber fuel hose has come off or is torn at the clamp....Usually, the problem does not appear until the tank gets below half full because the pump itself sits about half way inside the tank so the problem is hidden...think of it like cutting a big hole in a straw then trying to take a sip....nothing but air... Call Debbie at PJ Grady and order a new hose or check out John Herverys website and order his new main fuel line kit.... Mike C 2109 [Non-text portions of this message have been removed]
