Fuel Line setup for A mintor 170

[Jerry Budd]

Uhmm... I'm not sure what you mean?  I assume you mean - have I used 
two of the 90 degree fittings (they're Tettra's BTW) for the fuel 
feed routing in/out of the fuselage?  If so, no I haven't but I have 
seen many others do that and it seems to work OK.  I haven't had any 
problem with restriction in fuel flow by routing the feed line 
through the vinyl grommets, they are simply there to prevent any 
chaffing with the glass fuselage.

The reason I route the fuel line through the fuselage wall vs using 
multiple fuel fittings is simplicity.  The fewer parts in the system, 
the lower the likelihood it can fail somehow.

I hope that answers your question?

Thx, Jerry
