Figuring out routing and connection and bending of fuel line from header tank down to gascolator, then from there forward to engine.
Attached fuel shut off valve at the header tank.
Next: measure, cut, measure, fit, cut...3/8" aluminum 5052 pipe for fuel line from bottom of header tank to gascolator. Got one whole bend in and put some clear plastic tubing on part of the pipe as anti-chafe.
