Bill & Dan,

Thanks for the additional info and thoughts. Classic lists the "matching" fuel filler hose and does show different parts for the 1/2 and 3/4-ton. I'm not seeing a "lower" filler neck, other than the connecting hose, so maybe that's what is different, in which case, all should be good with the "upper" from Classic. I will post what they say.

Otto, I meant to mention in my earlier post, I have used Caswell's gas tank sealer which works well. I believe the Eastwood stuff is similar and possibly the same. Thanks.
