For the fuel injector installation job, some people choose to remove the whole fuel rail. I chose to leave all the hoses connected and just unbolted everything required to move the fuel rail out of the way. After pulling out the stock fuel injectors, a ton of gunk is visible under the rubber bushings used to center the stock fuel injectors.
Those bushing came out after a bit of persuasion. They are sort of like old rubber hoses that haven’t budged in 15 years; you need to break the seal and then they pop out easily. And then spend some time cleaning out the gunk in the ports.
For fuel injectors, I got ID1050x’s from Real Street Performance which should provide plenty of headroom for my 500 crank hp target on 91 octane unleaded gas. However, they are not so big as to have issues with idling.
Sorry for the blurry picture. The metal spacer with an o-ring takes the place of the rubber bushing used with the stock injectors.
The o-ring seems a bit oversized for the bore in the intake manifold, so I had to use a socket with extension and a rubber mallet to get the spacers fully seated. A thin layer of oil should be used on all the o-rings.
You can tell the fuel injector spacer bushings are fully seated because the o-rings are no longer visible. Real Street Performance provides these plug-n-play OEM connector to ID1050x injector connector harnesses making the installation a literal snap.

That’s the same pump I put in my tow pig. It’s a supercharged 454 making 450 or better at the crank with north of 600 ft/lb per Whipple. I checked the draw on the 15A fuse and determined this wasn’t going to put it over so didn’t bother with the hot wire. I figure it’s still way more pump than the motor needs. The local shop recommended the AEM as a lot of the others seem to be junk. Knock on wood, so far so good for me.
The stock Honda pump power wire is only ~16 AWG which is good for roughly 15A. The AEM 340 pulls up to 15A, so it would really max out the stock wiring. I’m much of the philosophy of overkill sizing for better reliability.
