FIRST fuel injected J3 Cub? | O-320 to IO-320 Conversion

Our old fuel system was a bit janky. When I tried to get it rebuilt I found out I couldn't! No one made the parts. SO, instead of chasing the rabbit down the hole I got rid of what I had and partnered with AvStar to convert this Lycoming O-320 to an IO-320. You read that right, we're fuel injecting Red Rocket. Could this possibly be the FIRST fuel injected J3 Cub? Kinda exciting to say that!!! Follow along as we go through the process from start to finish. Fun fact, it's the same process for a O-360!
Couldn't have done this part of the build without AvStar! Make sure to check them out for all your fuel system needs! Injection AND carburation. www.avstardirect.com/

Great looking fuel injection system Carl. AVStar’a components should make the Red Rocket a stellar performer. Nice looking parts! That throttle body is a work of art. I’ve seen it up close.👍 Nice work on injection line routing, bending and support. Hope to be there for first engine start.🤞

Last week didn't go to plan. My daughter got sick and I stayed home with her for a few days. Poor little girl. Shes feeling better now so I can get back to work. A worthy interruption, family always comes first, but it took several days away from my work.

Cool trick to measure for the fuel injection line.

@flywiththeguys 8 ай бұрын

Thank you! It's worked out great so far. Probably going to use the same trick when I do the oil and fuel lines.

Pro tip: next time you heat a bolt or plug remove the Allen wrench before heating. I've had them twist off before because you've changed the temper in the Allen head. Sucks when that happens.

Good tip. I'll take that into consideration for the next time.

Is there a way to use the primer ports on the cylinder to install the injectors?

@flywiththeguys 4 ай бұрын

From my research you can. As long as the spray is behind the intake valve it should work. The problem you run into is getting the injector lines to those lower ports. Heat and baffling kinda become a problem depending on your application. I had a tight cowling, so I needed it up top.

Out of curiosity- isn’t fuel divider supposed to be mounted on top of the plate to separate it from the engine as much as possible to prevent excessive heating of fuel and fuel lines thus minimising risk of vapor lock?

@flywiththeguys 5 ай бұрын

Not to my knowledge, and I don't recall seeing a mounting orientation in the documentation. I've also seen them mounted both ways in different applications. My buddy runs his this way on his RV 10 as well. Same mounting bracket too.

Fuel injection in a 1940s plane? This guy is becoming a madman! Gotta stop him before he puts retractable gear on this thing. 😆

Red rocket... the name is becoming a brand cos this is not a regular j3 cub. Countdown to fly day

I wish I could set a date for it! Last week didn't go to plan. My daughter got sick and I stayed home with her for a few days. Poor little girl. Shes feeling better now so I can get back to work. A worthy interruption, family always comes first.

@@flywiththeguys glad she's better now. Just take your time. We're here for you and red rocket. Keep it up. One day, I'll start my own day one . Keep inspiring us.
