Glad you resolved it! Just curious, sine I am dropping my tank this weekend...what size are those two bolts for the straps? 9/16? I want to make sure I have a ratcheting wrench for it. LOL

LOL! Use a size 14. That's what I used. Make sure to have the tool to separate the fuel lines.

As promised, here's my follow-up. Partially, anyhow. I had the tank out and the new fuel pump on in about an hour and a half. Easy. I'll be putting the tank back in tonight as I had to wait for Chassis Saver to dry as I coated the whole underside above the tank with it. Hopefully my gauge will be fixed! Also, I did *not* need any quick disconnect tools for the fuel lines (even though I had them). All I had to do was pinch the clips and they popped out.
I was shocked at how the original filter was 1.) so incredibly dirty and brown and 2.) much smaller than the replacement. Was this your experience as well, OP?


Also installed the new vapor line with hose.

Good idea on that roll over valve vent line.

I replaced my rusted line with a hose like that some years ago (with the tank still installed) and its still good to go.
