Just figured I'd share this picture I took this morning when I opened the garage door.

1 hr. on the fuel lines.

Loosened the gascolator (who named that?), so now it was easy to crimp the clamps (duh!).

Line to the fuel pump is on!

And the line to the fuel selector is also on!  The manual says that line is 50", but I cut it to about 54".  Firesleeved to the firewall.  I'll clamp and/or tie down all these lines once more stuff is in - I want to know where everything is routing before doing that.

A small percentage of the bounty of raspberries off my bushes this morning.  Yum! 😁  Are you local?  Come on over!  There's way more than we can eat.

Of course the obvious solution to crimping the gascolator's clamps... is to loosen the gascolator clamps to the mount and rotate to be able to crimp it...  Will do that tonight...

2 hrs. mostly sweating profusely in my garage...

About here looks right (as compared to the factory photos).

Putting the large clamp around the gascolator.  I did have to bend the closer tab out to line up better with the other tab.  BTW, what gets inserted in that top opening (the red plug).  I'd assume some aluminum plug fitting?

Hmm, the spacer is too long (not tight around the gascolator and not enough threads visible on the bolt).  I cut off 8mm and that worked well.

The manual says the gascolator inlet is on the right and outlet on the left, but that doesn't make sense to me since that means your lines would need to cross (not that that matters all that much, but still).  The outlet goes to the pump right above and the inlet goes to through the firewall a bit further left.

Since the turn is tight to get to the pump I figured I'd use the super-flex line I bought from Aircraft Spruce... Yes, it can turn a bit tighter, but because the walls are definitely thinner it was more easily kinked and I didn't like that possibility.  Especially because it would have firesleeve on it and I couldn't easily see if it was kinking (I tried it).  So, back to the supplied hose.

This routing seems to work well (zip tie is temporary).  I need to find out from the factory if they use Oeitker clamps on the gascolator because, for at least the outlet, it will be hard to crimp.

3.5 hrs. on the fuel lines (work was done yesterday - you'll see below why I didn't post this update until today).

Until I get a larger clamp this will do to temporarily hold the pumps in place.

That works (for now).

Mom helping me put firesleeve on! 😁  Being a knitter for nearly 80 years, she's pretty darn dexterous!

Ready to crimp.

Crimped and firesleeve in place.

And wire-clamped.  This is line from the pumps to the fuel regulator.

Silicone tape on the end.

Using a claw-thingy on my torque wrench to torque the banjo bolt.

These are the claw-thingies. 😎

A little tight to get in there, but I got it done.

In place!

Another spacer on the way down to the pumps.  Need to keep things away from the space above the nose wheel spring since that can come up.

Routing it down...  The other fuel line is temporarily held up with a zip tie.

Locating where the gascolator will be.

Mom took a picture of me. 😁

Where I was last night.  Red Sox vs. Los Angeles Dodgers.  We left at 11 PM (4 hours...) when it was tied in the 9th inning....  Checked this morning and saw that they lost in the 12th inning when the Dodgers scored 3 runs.

Taken before the game started.  Do you really need 10 people to hose down the infield??  I like how the head-hoser has a blue shirt and all the rest are red.  Must take years of experience to make it to head-hoser! 😂

2 hrs. on the fuel system.

Thanks to PeterC in Australia for the tip from the factory on how to put on the firesleeve!    Clamp off one end and using a compressor with a simple nipple tip to blow air into the other end between the hose and the firesleeve.  That inflates the firesleeve and you can slide it on with relative ease.  It helped to have my wife to push in the hose while I applied the air hose.

I used the larger size safety wire for the clamps this time.

And you need more than you think to do a clamp...

Using the Clamptite tool to put on the clamps.  I made a video to see how to use this tool.

Using a Clamptite tool.

Works well!

All on and routed through the firewall.

View on top.

Tied them together with a long zip tie and short piece of the fuel hose.

In order to size the other hoses I'll temporarily put on the fuel pumps (still need a new manifold to fix a leak).  Let's see if I can get two clamps on...

Well, that wasn't too bad.

But...  Can't get the second clamp past the first one...  Hmm...  Need a different approach...  One large clamp and a couple of metal zip ties?

Well, ones on....  But, then I realized that I couldn't screw the mount to the firewall because the pumps were in the way...  Back off they come and I'll try the different approach tomorrow...

Earlier in the day I went to a BBQ of the Aero Club on New England (I'm a member), which having been formed in 1907, is the oldest aeronautical club in all of the Americas!

And for your viewing pleasure, this is a lily from my front yard.

1 hr. on the fuel lines.. Until I was stumped again.

Since I got the sealing washer I needed to do the banjo bolt and new nipple change on the fuel regulator, it was time to set my torque wrench to 133 in-lbs (15 Nm).

Washer on, torqued and torque sealed.

As advised by the factory I took off the return line banjo bolt and crimped the clamp.

Also torqued to the same value and torque sealed.

Hmm... Putting on the supplied firesleeve seems impossible....  No more than 8 inches or so and the cumulative friction makes it impossible to push it more.  The sleeve is about 30" long, so coming from the short end wasn't going to work either.  Wrong size?  Something I can safely use to lubricate just enough to slide it on?  Stumped for now on this....

The 8mm (5/16") ID fuel line is 15mm (a bit less than 5/8") OD.  Is this firesleeve the right size?  Time to ask Mr. Google and the factory (though it's now nearly the weekend in SA).
