While i was trying to disconnect the union where my line broke from the fuel pump bracket {sender} I broke the plastic line with the rubber hose . Is there any way to splice it?? The next union is between the cab & frame & very rusty.

 

Yes using Fuel injection line and fuel injection clamps .

Last i bought the line was $7.00 a foot

 

Double check to get the right stuff. "fuel injection" hose and clamps are right next to the regular fuel lines/clamps but they are made for the higher pressure that you need. I fixed a small leak like this last year and it has held up fine. Buy the smallest manual pipe cutter you can find to cut out the old metal line. No risk of fire that way.
