Did the exact same thing... I can get to the filters and pumps through the access panel(albeit with a few 4 letter words and scraped knuckles).

Dan,

Those are steel fittings. The hole is for the nose gear bolt. I have SS plug that will be sealed in.

Got it, thanks.

I'm curious...a builder-at-large question. Traditional firewall layouts serve traditional installations. This is EFI, so no engine driven pump. Has anyone thought about moving the bulkhead fittings up high and off to the side, then plumbing direct to the fuel rail, rather than punching through low and centered, in the firewall's hot spot?

I hear you. I did it this way because of Van's heater layout. Wanted to use as many of the factory options as possible. Makes for a clean installation. I realize that this is the hottest spot in a fire event. That is why I installed steel bulkhead fittings and SS braided-fire sleeved lines on the firewall side.

In the event of a fire, I am more worried about the floor of the aircraft, however I am not going to modify that part of the aircraft.

That's what I've done with my alt engine install. Throttle cable and most wiring go through a flanged stainless tube above the top left motor mount bolt ( technique described in the AEC book), and fuel through a bulkhead fitting just below and inboard of the same bolt. No stretch, and minimal flex by exiting there with my configuration, with throttle and fuel at top left of the engine. Fuel line follows motor mount to the area near the fuel distribution block.
