Barrie" Subject: RV7-List: Fuel Inj. ret.line --> RV7-List message posted by: "Darwin N. Barrie" 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?? Darwin N.

Eggenfellner Subaru has a most excellent installation manual that covers all this and much more in great detail. http://www.jlc.net/~fcs/EAA_IG/EAA_RV_IG.htm 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. http://brian76.mystarband.net/FuselageNov03.htm -----Original Message----- From: owner-rv7-list-server@matronics.com [mailto:owner-rv7-list-server@matronics.com]On Behalf Of Darwin N.

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! -Mike Kraus ________________________________ Message 4 _____________________________________ Time: 05:07:45 PM PST US From: "Stein Bruch" Subject: RE: RV7-List: Low Oil Temps --> RV7-List message posted by: "Stein Bruch" 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)!
