Jun 23, 2020 2 Fuel pump assembly Category: Fuel System
I'm a pretty simple guy but I'm always impressed when fuel lines I built two years ago from the front of the RV-12, with several bends, end up mating perfectly with the banjo fitting on the fuel pump assembly that arrived last week. OK, I probably could have made it 1/16" shorter.

I found a very short piece of ATO-035x3/8 to use to make the two inch run to the fuel drain assembly. It was part of the tank test manometer (which didn't work on this plane because it's impossible to seal up the filler hole). Later, I heard from Van's that it was OK to use that two-foot length in the powerplant kit, but I've got more to make and I'll use it for that before the 8 feet of coil I ordered last night shows up.

I sure hope the new design with sealing washers works because there's a LOT of potential failure points here. I'm being super careful.

This is the old design where the fuel line comes under the shut-off valve instead of looping aft around it so I installed the standoff and firesleeve as directed in the SB to avoid chafing.

That's going to be a tight squeeze there when the tailcone goes on.

There is one electrical connection there and the wiring is apparently in the final subkit. Not sure how hard that would be with the tailcone on but I would like to get aft skin, window, and canopy done at some point. After the cowling maybe.

It's good to be working on the project again.
