The engine in earnest

I hung the engine on N614EF more than a year ago, but now that the cowling is -- mostly -- done (structurally speaking ), I'm trying to get going on serious work to get the engine all hooked up.

Yesterday I spent a ridiculous amount of time getting the ground strap from the engine case to the firewall hooked up. I wanted to make the power line from the contactors to the alternator but two things cropped up -- I can't find any of the paperwork (or wiring) for the alternator (which I put up last winter), and I've noticed some builder sites are running a #8 wire, and the instructions call for a #2. I'm going with the #2, but don't have the connectors for the wire. More ordering. More delay. More shipping.

So today I'm adding on some fittings for the oil case which will attach hoses to and from the oil cooler. And, of course, I ran into problems.

Here's one:

 

This calls for a straight fitting, but I have the right angle oil filter adapter on this IO-360 engine from Mattituck. What should I do here? A 45 degree fitting?

I also installed this 45 degree fitting on the other oil connection. But it's unclear how I "clock" it. Which way should it be pointing?

I also looked some more at the fuel line from the pump to the fuel servo. On a 7A, there's VERY little room to run the thing, especially with a vertical updraft engine. I need to figure out how close to the heat shield on an exhaust, the fuel line can come.

Start. Stop. Start. Stop.
