I can't find any information on the placement of the fuel injected return line
to the tank. I was thinking of placing a fitting on the large plate on the root
rib near the top of the plate. Any help??

The Van's FI pump setup for Lycoming FI does not use a return line.
Eggenfellner Subaru has a most excellent installation manual that covers all
this and much more in great detail.

TRUST ME on this; in the cabin, fuel supply goes on TOP, then return, then
brake lines. Try it another way & you'll be redoing it, as I did twice.

I have searched the archives and did not find too much informative. Maybe I
did not search it properly.
My RV-4 runs very cool, too cool. My CHT's are around 380-400 F Max, and my
oil temp is only around 150F on a hot day.... I have a firewall mounted oil
cooler, 2.5:" scat tubing going to it, I have checked the oil temp probe and it
is accurate. I cannot seem to get any warmer temps unless I use duct tape to
block off air to the cowl.
I tried an adjustable door to the oil cooler to block off the air, but it
only helped increase the temps by about 10 degrees. I plan to install an
aluminum blocker on the baffles to simulate the duct tape blocking air into the
cowl.
Does anyone have any other ideas that I can try? Thanks for any help!

Hi Mike,
I wouldn't be too concerned with your CHT's, those look fine to me.
Depending on which engine you have, that temperature is just about perfect.
Youre oil temp does appear to be a bit low, though. I'd shoot for 180-200oF
for your Oil Temp. If I were you, I'd leave the air intakes to the engine
alone, as the CHT's are fine. I'd either partially block the air to the oil
cooler or put a partial blocking plate behind it. That's what those of us
up here in the frozen tundra (MN) have to do during the winter. That being
said, I also use the customized "duct tape" winterizing kit for my cowl
intakes when the OAT is below 20oF (looking forward to 3 more months of
that)!
Cheers,
Stein Bruch
