so it's pretty common knowledge around here that using a 1/2" driver on the filter caps is a no-no, and to use the large socket instead. well i've been using neither of those provisions the last few times i've done filters.
perhaps this has been discussed before, but i've not seen it come up in the almost two years i've been dropping into the 6.0l forum:
i've been using an actual oil filter wrench that i've had sitting around from previous vehicles, that in a pinch i tried on the oil and fuel filter caps.. and it works like a dream.
it puts a nice even pressure around the perimeter of the cap, and the harder you turn the more it grips. it has proved to work pretty well for removing the lower fuel filter, with the front driveshaft in place (once you figure out how to work with it in that spot)... alot less cumbersome and more compact than a ratchet. again, maybe this is common knowledge, but i hadn't seen it discussed and thought i'd share.
