Advice 1988 Ford e150 selector valve bypass


I’m seeking advice about bypassing my front fuel tank on a dual tank 1988 Ford E150 van. The selector valve is causing my front tank to overflow and create uneven pressure and stalling at inopportune times in traffic. I read a thread about bypassing the front tank using a hose and clamps. I need to determine the size of the hose I need and the trick to the quick release stock hoses.
