Manifold Flow Control Orifice

corey    Customization, Hardware, RV Project     engine, manifold pressure

Name: Brass Flow-Control Orifice, 1/8″ NPT, 0.032″ orifice
P/N: 2712T478
Purchased From: McMaster-Carr

Description:

Brass fitting with 1/8″ NPT threads .. male to female. This particular one has a 0.032″ flow restriction orifice.

Comments:

This will be installed on the engine’s manifold, on the manifold pressure line. The purpose is to prevent the manifold pressure sensors from experiencing rapid fluctuations in pressure, making for a more even response. I’m worried this will actually cause minor tuning problems with the engine ECU (which uses manifold pressure to determine appropriate amounts of fuel), so I will have to experiment a little.. and possibly move this to a position after the ECU’s manifold sensor. (Which would require buying a different type of orifice).

New Fuel Filter from Aeromotive

corey    Hardware, RV Project     engine, fuel filter

Name: Aeromotive 100 Micron Inline Fuel Filter
Model: 12304
Manufacturers Page: Aeromotiveinc.com
Purchased From: Summit Racing

Description:

Replacement for the original two simple paper fuel filters that came with my E6 Eggenfellner engine. The 12304 has ORB-10 ports and requires an adapter to convert to AN sizes.

Comments:

Need a way to mount this securely, which requires something with a 2″ ID. I am going to try to utilize a large cushioned clamp but may end up buying the purpose-built mount made by Aeromotive. For converting to AN sizes, I purchased ORB-10 adapters from Summit that convert to AN6 and AN10 AN8. The AN10 AN8 male will connect to an AN10 AN8-to-NPT adapter on the fuel pumps. The AN6 male will connect to the fuel input coming from the fuel selector switch.

FueLab Fuel Pressure Regulator

Name: FueLab EFI Regulator, Mini In-line
Model: 54501-2
S/N: 300744
Purchased From: Club RSX

Description:

Replacement for the original Bosch fuel regulator that came with my E6 Eggenfellner engine. This model has AN6 IN/OUT ports, a port to read manifold pressure, and an additional port for a fuel pressure sensor.

Comments:

Nice mounting bracket to secure on the firewall. Need to find 2 steel AN6 unions to connect to the fuel rail and the return fuel line. This model is red/clear but there are other color options. I’d like to use the front port for a fuel pressure gauge but I don’t know that there will be enough room; an elbow may also not make enough room, but we’ll see.

Prop and Engine and Panel

corey    News, RV Project     eggenfellner, engine, prop, rv

I just found out that my Eggenfellner Subaru engine is shipping this week! I can’t wait to get it. The cowl and the new ‘official’ manual will be delayed, I’m told – but I really just need to get my hands on the fuel pumps so I can start putting in fuel lines.

My constant speed prop and avionics panel should also be shipping this week, so I’ll have quite a Christmas in July if everything gets out on time.
