FWF fuel system installed

I replaced the original EFII hoses between the cylinders with the much nicer Aircraft Specialty ones, and attached the hoses to the regulator and post filter:

To use the cross-over hose from AS, I had to thcange the fitting on cylinder 1 to an AN826-6D ($15.50 at Spruce - what happened to hardware prices!?):

Multiple fittings to connect the left forward injector to the cross-over hose

I'm still puzzles by having to use 3 fittings and a shorter hose on cylinder 2, but they say it's for better fitting the cowl so I believe them. Some day I may change that to another AN826 and a normal-length hose, after I know exactly how the cowl fits there.

Attaching the post filter was quite annoying - I tried the special Adel clamp tool, but the bolt was too short for that, so we ended up developing a new technique for these (which I'm sure someone will say is wrong - but if it worked, is it?) - we compressed the clamps, then ran safety wire at the base of their flange to hold them closed, and with that it was (comparatively) easy to get the bolt and nut in place:

The fuel pressure regulator conveniently had a 1/8" NPT port on the side, so I installed the fuel pressure sensor there:

With this, there are only a few finishing steps left for the FWF fuel system - supporting the engine hoses again, adding the induction system drain hole, and securing the cross-over hose.

Fuel pressure regulator attachment

As the last firewall penetration (and start of the FWF fuel system), after lifting the engine and temporarily attaching it into place, I attached the Aircraft Specialty hoses to position the EFII/Aeromotive fuel pressure regulator:

At first I was having trouble finding a position and the hose seemed to short, until they pointed out that the hose can bend at a much smaller radius than I was trying, and then I found a good position, marked it, and then drilled the bracket holes (the holes are not accessible without removing the bracket from the regulator), and made a doubler:

Once that doubler (and others from the avioncis section) get riveted on, I can then insulate the firewall, re-attach the engine mount, and complete all the other FWF sections.
