[Vwdiesel] Banjo hits sour notes

[Justin and Michella Bennett]

Yes.  The pinhole is caused by the erosion of the line material by the 
fuel as it makes the turn in the bend.  High pressure fluids that are 
moved by a piston type of pump seem to cause this more than fluids ran 
by rotary pumps.   Unfortunately unless you own an ultrasound or x ray 
machine you cannot measure the amount of wear in the corners.

>  Seems the 2nd from flywheel end metal line from the injection pump (85 Jetta TD engine) has sprung a pinhole leak where it turns to go into the injector. 

>  I didn't expect a metal line to develop a pinhole leak. There wasn't any metal to metal tube rubbing. Biut the injector lines are missing the rubber separators, so maybe some vibration created a stress point. Anyone experience this kind of problem?
