Ever since I've replaced my headgaskets I put dipaco fuel return lines on it, the yellow fittings with the red hoses .

But they crack like this.

I do suspect high return rates on my injectors, but it's still silly. Every three month a random hose pops.

This time it's very obvious the hose became brittle and cracked
