Recently, a squirrel paid a visit to the engine compartment of my 1999 VW (it's a diesel 1.9 TDI). Besides leaving some crabapples as gifts, it chewed clean through one of the fuel injector return hoses. I didn't discover it until reaching my destination and smelling/observing the spilled diesel which was bathing the front of the engine. I did not start the car until I tracked down a piece of replacement hose (not easy due to the location and the fact it was a holiday evening).
Could I have plugged or otherwise sealed the ends of the cut hose and driven home without doing any damage?
