I'm in the process of getting back to my RV-6A project after 10 years or so of having it mothballed. There are a few items on the plane that I look at now and would like to improve how I originally installed them. For example, the fuel line connection from the firewall to the filter was originally configured as an aluminum tube:
I'd like to replace that tube with something more robust, while minimizing the ripple effect of moving too many parts around. The problem is that the distance from flange to flange is only about 4 inches, so it's really too tight to connect from flange to flange using a hose with a 90deg fitting on the end that would connect to the firewall fitting.
The options I've come up with so far are:
1) Move the filter to a different location further away from the firewall fitting. The downside to this is the ripple effect on other parts and I'd have to remake the heat shroud for the filter. Doable, but hoping for an easier solution.
2) Make a tube similar to my aluminum tube, but made out of stainless. Tom at TSFLIGHTLINES has offered to make this up at a reasonable cost. Only issue I can see with this is whether or not there would be a problem with vibration stress cracking over time.
3) Make a "U" shaped hose with 90 degree fittings on each end. Other than the cost, this seems like it would work.
Anyone have thoughts on which way to go with this connection?
