I live in Tucson, AZ with the temps around 110F to and have never had an issue. The one thing to remember here is not all aircraft air flow and fuel hose installation is the same. Some don't have fuel re-circulation lines. So any heat build up on fuel hose can make a difference. The key may be re-routing hoses, make sure they are all in fire sleeve, wrap the exhaust pipes, make sure you do have unobstructed cool air flow through the cowl.

Do you have a fuel return line on your aircraft? If so it is a plugged return line or a fuel tank venting issue. On my 75 year old Ercoupe, it will not pull the last 25% of the fuel from the tanks if the fuel caps are not sealed properly or a cap is on backwards pointing the vent toward the rear of the plane. It also acts up if I am above 8000 ft. Now that you have a backup electric pump, you might be OK. My back up electric pump will not overcome the venting situation. Watch it carefully when you get to the same fuel level in the tank. Dropping in altitude will allow fuel to start flowing again if it is a venting issue.
Yes Tim, I have a fuel return line and it is a plugged return line.
Thanks for your suggestions. Up to now -- after adding fuel -- I turned the fuel caps by hand until the cap was tightly in place with the venting device pointed backwards. There is a tool to tighten the fuel caps even more which I never used, believing that the caps were sealed tightly enough. Will now use the tool to really tighten and seal the fuel caps.
