Brief Description: Fuel line holes in foreward ribs
Measured and drilled holes for fuel tank line. 640-V-8 syas that the line should go up about 12 degrees to the #1 rib. I measured 12 degrees from rib #5 which is basically the inlet to the fuel tank and 12 degrees would put the line well above the top of rib #1. After looking carefully at the factory pictures and asking other guys on the matronics forum I realized that it should go up "about" 12 degrees from rib #4 to rib #1. Mine ended up at about 10 degrees and everything worked out fine. I wrapped masking tape around a sharpie until it was snug in the output hole of the fuel tank. I then slid the tank up against rib #5 and just drilled a hole where the mark was. I went up slightly ( a couple degrees) top rib #4, the went up the 10 degrees from there.
