ID parts/plumbing for 1/12 Wolf WR1 Ford DFV

Hello,

The 1/12 Tamiya Wolf WR1 kit has some parts on the firewall I would like help identifying. The parts seem ready for plumbing…I just don’t know what kind or where to plumb them to.

The parts are on page 9 of the instructions, step 6 & 7…parts F2, F35, H27, J8/F34/G38 make a subassembly, and lastly J12.

thanks.
