For the engine to turn it needs air, fuel and electricity. Today I begin by tackling the fuel part, at least waht's forward of the firewall. This is the hose between the gascolator and the mechanical engine driven fuel pump. The hose seems slightly long but the one supplied by Vans was too short and onl 1" shorter. This is the other side of the mechanical pump. At the outlet I installed a T fitting on which there is a retrictor fitting an a hose where the fuel pressure will be measured. The hose I'm holding will get connected (via an elbow fitting) to the T, the other end of the hose will get connected to the throttle body. In the background, the copper fitting is for the fuel pump overflow. This is the throttle body with the hose coming from the mechanical fuel pump. This is the back of the throttle body with the hose sending the metered fuel flow to the divider. I will replace the elbow fitting with a straight fitting. And this is the divider on top of the engine. And this is the end of the fuel pump overflow hose. I still have to attach it correctly. The installation is only provisional, but took quite some time as ther are a lot of interferences, space is scarce and some parts still have to be bought.

Onlay small tasks today as I might be called anytime being on standby at home. First I glue the forward ramp seals to their respective bracket. I then sand the top cowl around the oil door and do some touch up. I use the remaining epoxy to fill the thousand pinholes. The quality of the finish leaves to be desired. I then do some tweaking on exhaust hangers. And finish today's session by cutting the nos gear leg fairing as it was too long and interfering with the lower cowl support bracket.

The exhaut gets now bolted to the supports. After a few test installation of the lower cowl, vereything looks good. The gaps with the engine mount, cowl and fuselage are correct. next task is to verify the position of the heat muffs around the mufflers. No problem on the right side, I even put some tube for test. On the left side, the postion of the various flanges is interfering with the cowl or the engine mount. The solution is to unscrew it and turn it around. This is with the screws off. And again after being turned and the screws back on. I have also installed the oil cooler on the aft baffle. I'm using large washers that have to be modified. I also installed the two fittings.

Before hanging the exhaust, there is some small work to be done on the support brackets. All parts get correctly marked before all is uninstalled. The orange tubing will be replaced once I receive the correct part. The inox tubing tends to slip ou of the rubber tubing and to avoid this I made some small grooves with a saw blade while the tubes where turning in the drill press. It's not very professional but should be enough. And to be on the safe side, I did a small flare on the end of the tubing. Working time on this subpart Today : 1h (Total : 86h) |

I think that from now on, a part of the workshop will always have some parts where there is fiberglass work to be done. I begin by working again on the oil door. First a rough sanding of the work done last time. Then the edges where the door lies when closed have to thickened by some filler. Working time on this subpart Today : 1h (Total : 50h) |
