Has anybody used a flexible necked 'pump' type oil can for this? (Sort of like the tin man used in the wizard of oz). I need to get in there and check mine, and saw the old Moore type, and was hoping to come across one of those, but it looks like that won't be an option. I figure it would take a lot of squirts to fill it, but for just a top off, it seems like it might work with a long necked oil can. ???
