The fuel line on the rear tank keeps blowing apart I replaced the fuel filter could the fdm or fuel pump cause this problem it only blows the line closest to the tank

Is this a rubber hose? Are you replacing it with hose that is made for fuel and pressure?

Can you describe where it is located. I have to be honest, I have never seen plastic fuel line. Rubber fuel line is common and steel is always used, but I never saw plastic.

Can you upload a picture for me to see what you are dealing with? I feel that should be regular rubber fuel line and not plastic. The plastic won't withhold the pressure.
