Troubleshooting plans

1) disconnect the fuel cap
requires: just that
purpose: checks if negative pressure is building up for some reason

2) Reverse the Fuel send and return
requires: loosening connectors and switching the hoses to the opposite fuel lines.
purpose: checks if the screen on the fuel send is getting clogged.

3) Bypass the Fuel Selector
requires: 1 pcs from rona to adapt the two fuel hoses.
purpose: Checks if the Fuel selector is the problem

4) Replace the Fuel lines with clear braided hose
requires: Removal and replumbing of all my fuel lines (much work).
purpose: allows me to see where the bubbles are entering the line and isolate the problem.

Well that helped me organize what I plan today tonight or tomorrow morning.
