Title: Oil Heat
Post by: GlennBob on June 06, 2007, 01:40:43 AM
Waiter or Drew,
I'm about to tackle hookin' up my oil lines to my second oil cooler under the GIB thigh support. I bought the aluminum lines you specified (Waiter) from Spruce, and I remember you telling me that the flare angles for aviation were different than for automotive. I have a couple questions.
1) Can I still use automotive fittings and flares ? Heavier ?
2) I plan to use flex lines from the engine to the firewall and solid lines after that. How do I anchor / transition at the firewall ?
See pics.

GlennBob;
I would attempt to use aviation, if possible (38 deg).
I'm going to install bulkhead fittings at my firewall. Its an AN6 hose fitting on both sides.
Depending how far I get with the design, I'll at minimum install the bulkhead fitting on the firewall, connect the hoses on the engine side, then just install a plug on the hell hole side for now.

Use the aviation flare (37deg). Don't use the automotive flare (45deg)---not enough surface area---prone to leak. You can get an adequate 37 deg flare tool from Summit for a fairly cheap price (30-40ish dollars).
