Gas overflow fix hose problem with GM hose
So I have had the GM fill hose installed for several months now with no problems at all with the overlfow. However, over the last month or so, I noticed that the gas pump would click off more and more, until within the last week I've had to pump the gas extremely slow so as to keep the handle from clicking off. Today I took off the GM hose, which still looked fine on the outside, no visible kink as I had installed a hose clamp on the bend. But looking inside, it seems the inner part of the hose had separated at the bend and bubbled inward, restricting the flow of gas and thus causing the pump to click off. The fix was easy, I cut out the flapper and stuffed it in the old OEM hose that I had kept, put a hose clamp around where the flapper sits, and just filled it up full speed and no overflow. Hope this helps anyone with this problem. Pics of the GM hose below.
