OMG!!! those little push-in-pull quick disconnect fitting were a beeeyotch to get loose.(even with the special tool) My arms kept going numb trying to hold them up working on it, then after straining and jerking for a few minutes they'll finally come loose. Then your knuckles get the meat raked off of them.
and of course you'll get gas and chunks of rust and mud in my eyes, lol
I've had to change this filter 3 times in the last year and a half due problems with moisture/water and ethanol gas. (So I think)
