I cut off my original 72 neck and tig'd it on to the new tank. I picked up a new sender with filter cheap, and replaced the brass float with a plastic one from a Jeep, fit perfectly, and should never leak and fill with fuel. I found the info on the Jeep float on here as well.

I think the tube from the neck to the tank it to aid fuel filling and allow air to evacuate the tank and not blow fuel like a whale port. May be wrong? if so, someone will correct my thinking hopefully.
Where did you get your tank? Brass float? The buoy I called a ball in the pic.?

Tell you what, don't be in a hurry to dry these tanks. The blower has been running 45 minutes or so and it's still damp along the seams.

Much of the info. applies to all 67-72 GM trucks, and to a lessor degree all 67-72 GM vehicles. My build thread, and more on the guide https://67-72chevytrucks.com/vboard/...d.php?t=730025
