New Fuel Pumps

corey    Hardware, RV Project    

Name: Protek Fuel Pump Module
P/Ns: FPM-1 & FPM-2
Manufacturer’s Page: ProtekPerformance.com

Description:

Replacement for the original fuel pumps that came with my Eggenfellner E6 engine.

Comments:

I like this for two reasons: 1) they are high quality Walbro GSL 393 pumps, 2) the manifold they are mounted to allow me to connect with standard AN fittings. With the standard Eggenfellner setup, you have to convert from rubber EFI hose to a barbed NPT fitting to an NPT to AN adapter. This setup also handles feeding both pumps very compactly, rather than an extended T with rubber hoses.

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

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.

Got ‘em

corey    News, RV Project    

I finally got my engine and panel in – actually got them a couple of weeks ago, just haven’t posted anything about it yet! Only waiting for a couple more things now: Cowl (this covers the engine), my propeller (any day now), and some small but important fuel things.

I’ve been waiting for the fuel components for awhile and I finally got the last piece a couple of days ago. Turns out it can’t connect/couple with the other component I need it to connect to! (From the same company no less!). So it looks like I’ll need to upgrade my fuel selector to the newest version so I can use the extender I need to use.

Here’s a quick picture of my engine, as it looks crated in. This is a 2007/2008 Eggenfellner E6 6-cylinder Subaru engine (normally aspirated).

And here are a couple of pictures of my panel, as delivered by Aerotronics. Very nice wiring in the back, I hope I don’t have to break any of those bundles!
