I run 3/8 alum pipe with a v notch at the bottom.

Sometimes the racor housing can corrode and have pin holes
as well, but probably not his issue.

How old is your fuel line? Some fuel lines have an internal liner that has been known to delaminate and cause a blockage!

Also, you mentioned recently cleaning the tank. Did you use any sealant on the sending unit gasket? Years ago when I was young and dumb, I used RTV/ silicone, which is not resistant to gasoline, and a bunch of it got into the tank and plugged the fuel line, causing exactly what you’re seeing! I wouldn’t use any sealant but No. 2 Permatex, the type that does not harden.
