As alluded to by others, there has been an update to the RV-7/8 fuel tank design that allows for providing predrilled z-brackets for the fuel tanks.

At the time of the change-over in part production, the updates to the plans were not yet completed but since the change in actual build process is rather minor (the updated parts basically just pre-complete some steps for the builder) the decision was made to start supplying them in the kits ahead of releasing the updated plans.

Builders that have the new parts should just skip the steps in the manual related to marking and drilling the z-brackets for the bolts. Then install the nutplates, mount the z-brackets to the spar web with the specified bolts, and cleco the baffle and ribs in place.
From that point on the build sequence should be the same as described in the manual.

Scott - thanks for the explanation of the parts and plans difference. Seeing what the legacy kits required I think this was a nice kit upgrade!

Default Order these to replace my old ones

Can I just order these new ones and put my hours to use on some other task? I have a Slow Build Circa 2008 kit.

The updated parts should be compatible with any legacy fuel tank parts in the RV-7 & 8 wing kits.

TANK ATTACH BRACKET
T-712
$2.25

Will the ones that show up in the webstore be the old plain ones or the new and improved?

I do not need them yet, but for $2.25 I think its a good conversion on $/time

Just completed the pre-assembly of all the components, the new Z brackets are flawless. Vans even offset the inboard attach holes for socket clearance!
