The two blue fittings on the pump are not AN816. No ”AN” marking. AN816 fittings are pipe thread not straight thread.
Remove the AN look alike from the pump. Carefully transfer the “O” ring to the blue fitting on the prefilter. (No idea what the “DT” marking on the blue fitting means). Then everything fits well. All matching straight threads.
I’ll trim the mounting plate so everything lines up.
Looks great Darrell!
Thanks Tony,
The more I thought about it I decided to go with a serviceable filter and not have to de-fuel the S-21 just to change the fuel filter.
Added a shut off valve from Russel and a filter from Sumit Racing.
A little late, but here is a link to assist with any future needs.

Or something else missing..
On a flat surface filter and pump not in-line. Looks like spacers are required under the pump.
