ECI Engine Part Identification/Setup

[grayforge]

My ECI IOX-370 engine is here and hanging by the top 2 bolts on the mount so far. Sump is the ECI Cold Air Sump. Fuel injection is Precision Silverhawk.

A couple questions about engine components before my "Firewall Forward" book arrives.

1. What's the port pointed to by the leftmost arrow below? Is the one on the right Oil Pressure?


2. How about the port on the mechanical fuel pump in this photo? Fuel pressure? What do most do, plug it or add a sensor to a block on the firewall with hose from here?


3. What's this silver thing? Anything I need to do with it?


4. I think ECI ran-in my engine with a different Throttle Body since the outlet hose seems to be sized to an outlet on the bottom of the Throttle Body instead of the outlet on the top shown here. So I either need to shorten the hose or move the outlet to the bottom. What do most do?
5. Also, is this the proper orientation of the throttle body?
6. Will standard Vans throttle & mixture brackets work?


Thanks!
Russ

1---tach drive??? not sure ?? Pull the cap off and look in there.

2 is fuel drain------if the diaphragm ruptures it keeps fuel out of the crankcase.

3 is vernatherm.

5 I dont think it matters, as there is no float bowl. Whatever fits best, and works with hoses and cables.

3 look like engine oil press adjustment

Head slap time, I think you are right.

For #1, looks like there's a socket head in there, maybe for an allen wrench. So Tach driver sounds reasonable. I wonder if I need a real cap for this instead of the plastic one.

ACS sells a very nice one with a hex head and safety wire holes so that it can be properly secured.

1-Tach Drive

2-Drain port in case of internal fuel leakage, this one gets plumbed out the bottom of the cowling.

3-Oil Pressure Adjustment and it looks like its bottomed out in the max pressure direction. These normally have about 1/2" of the threads showing. Be cautious of first start as to what the oil pressure does.

Very cool. Thanks for all the info!

Wow I'm surprised you guys are building a plane and don't know this beforehand!! Or after!! Cmon!!

1. Tach drive
2. Oil Pressure port.
3. Oil pressure regulator adjustment.
4. Fuel pump overboard drain line
5. Metered fuel line fitting (connects to the line dangling there next to it.)

Ya gotta learn sometime, which is what I'm trying to do now. What are the best resources for this info? I have the Lycoming engine book, but it's just a series of hints. Not sure if Vans includes this sort of detailed information in their FF kit.

The other resource I have is the Firewall Forward book by Tony Bingelis. I received it yesterday and went through it last night. Unfortunately, it's just a high level overview of a variety of FF items, not a deep dive into "What's needed to connect your engine". :-(

Also, with cars, I'm used to taking manifold pressure off the intake manifold (hence the name :-) ). For the Lycoming, it looks like you get it from a port under the cylinder head.

I wonder if each P-Mag gets its MAP line connected to a different cylinder or if you just use one cylinder to drive both P-Mags and your MAP gauge. I suppose one could tie 2 cylinders together to average out the manifold pressure reading a little bit.
