Called Van's Support and got some questions answered. - Fuel/brake lines - push through support brackets, bend and then flare? Yes, mostly. Might be able to make some bends away from fuselage, but all final bends and flaring will be with the tubing in the fuselage. - Location of holes in firewall for brake reservoir and fuel bulkhead fitting. Drill now or wait for engine? Drawings probably good. May want to check on VAF. I currently have the drawings that came with the kit (probably the best match for the parts I received) and the 2017 USB key I purchased. I found out I can also download all the latest drawings. I'll use the drawings that came with my kit and cross check against the latest drawings to see if there were corrections or changes that might be helpful. - Type and material fitting for firewall fuel line? Found my current drawing calls for aluminum. Will check the latest to see if it is still aluminum. - VA-107 brake reservoir and fitting doesn't work? Fitting too large? Didn't ask. Measured more and seems the fitting is oversized. I'm ordering the new fitting so I'll just try it and see if I still have a problem. Found a support bracket I've been trying to find for days! Test fit the fuel pump housing, valve mounting plate and valve cover on the bench. Studied Andair drawings, marked and drilled the 1" center hole and three #8 clearance holes in a valve mounting plate. Need to decide if the mounting plate with the bend is better than the flat one and then finish whichever one I select.
