Thread: turbo to pump pressure line

1994 2.5TDi Discovery. For some reason, the pressure hose from the boost side of the turbo to the injector pump keeps blowing off at the turbo (with a significant drop in performance, as the pump is not delivering enough fuel) - anyone have any thoughts? Thanks.

The turbo end fitting ( A piece of hose on the barb end with the turbo boost tube pushed in the other end and secured by spring clamps) is a little iffy at best. I've replaced mine by unscrewing the barb fitting, removing the piece of rubber hose, and using a push fit air connection (Pirtek) directly onto the plastic tube. Use some threadlock as well.
