Matt,

I found that old listing, and now I know what you mean by "high". To
summarize what I think I read, you ran two 3/8" fill vent lines to the
front and up into the space behind the interior panel that covers the
plumbing for the fuel filler neck. And then you teed them into a half-inch
hose right below where the half-inch hose fits on the filler neck.

And the reason is that the main tanks fills first--the flow from the gas
pump pushes fuel into the rear tank before doing much filling of the front
tank, and when full it blasts a shot of gasoline into the fill-vent tubing
before much fuel enters the front tank. With the TEE in the rear, that
blast of fuel blocks air flow in the vent from the front tank, forcing the
front tank to fill very slowly and unhappily. So, the first 25 goes in
easy, and the second 25 doesn't. With the TEE in the front and right under
the filler neck, that blast of fuel doesn't make it into the fill vent for
the front tank, and it can vent as it fills as it should. The usual
practice of filling on the slow setting is a partial solution because it
makes it easier for the tanks to equalize a bit as they fill--there isn't
quite as much dynamic flow pushing past the side opening into the front
tank.

Did I get that right?

I'll do this in the future--don't have to drop the tanks to do it and I can
manage this one in my driveway.

The mod that I did to the fill vent can be read under "Recommending High T"
