Hi all - I cannot for the life of me remove the old injector rubber hoses running from the fuel rail to the injector. The part I cannot remove is attached to the fuel rail. I've cut the fuel hose in multiple places at the fuel rail and it just will not come off. Will that circular bushing which is at the end of the fuel hose slide forward under pressure to push the fuel hose off? If you all have any tricks, please l et me know.
