Installed the GascolatorInstalled the Gascolator
This was pretty simple except for the putting the angle fitting on the right. It wants to stop turning where "it" wants to stop turning. I think the hose will hook up OK though. I couldn't find the special lock nuts in the firewall forward kit. I noticed that they were listed on the firewall forward kit list but weren't in the kit anyware. Then after digging around, I found them in the fuselage kit contents. Weird huh?

My first attempt didn't work. It was just a gentle curve from one component to the other. But I couldn't get between the two fittings without messing up the ends. So I took the first attempt piece and made a new one, using the first one as a template. This time I made an "S" turn with it. This allowed some flexibility to put the line between the fittings and stretch it in between the fittings for the final fit. I made a real mess with the thread seal on the gascolator bracket. By this time I really didn't give a crap how messy it was.
Now for the vent holeNow for the vent hole
I was really scratching my head on this one, remembering what a pain it was using the 2 inch drill bit I bought for the battery box. It worked OK for that application, but only because I had board behind the metal to support the drilling on the drill press. Not so here. I couldn't figure a way to put a board behind the firewall, much less trying to hand drill the hole with a monster bit in an electric drill. So I decided to go with my unibit, making connecting holes all around the edges of the hole. Then I used my Dremmel with a sanding drum to clean up the excess. I went through about 4 sanding drums in the process.

Here's my unibit and the Dremmel with the sanding bit. The drill is ancient but still works.
