Plug up fuel return like at tank....

[1974dodgecharger]

What is everyone using to plug the fuel return like at the sending unit?  I have not installed the lines yet but want to drive around with it plugged up.

Ideally a rubber cap with a clamp, ie a rubber hose closed on one end.  If that's not a readily available part then just use a piece of fuel line hose with a bolt in the open end.  Use 2 clamps.  1 on the fitting and 1 on he bolt.  Use a bolt that's a bit too big so you can heat up the hose to get it in.  Better safe than sorry.  I don't have to tell you not to do that near the tank right?
