varies miles...have resealed many leaking pumps. typically with biofuel and diesel use this will occur sooner than vehicles running just one or the other.

Fuel found after vehicle parked. Poor MPG. Inspected IP could see leak. Decided to install rebuilt injection pump and timing belt/water pump instead of just replace IP seals. Get rebuilds done at DFIS in Portland, OR.

Fuel injection pump replaced twice. Second time the dealer said it was probably due to use of biodiesel
