fuselage fuel lines
 

I'm sure this has been asked before but is there a problem with using flexible fuel tubing such as Aeroquip 601 to run from my wings to the fuel selector? I installed the al. tubing with less than optimum results and want to redo it.
Thanks

I used flexible hose. I used a short section of tubing to penetrate the fuselage to the wing, then had hose from there to the selector valve. Use 3/8" ID hose to make sure you don't restrict flow. Any good fuel grade hose and the AN fittings will work fine. I did use tube to the fuel pump and the gascolator.

I have flex hose from wing to fuel selector, then tubing foward to firewall.
