Tobin,

Excellent post. One of the things that has bothered me about the diesel oil
pickup is the integration of the pickup with the pressure relief valve in one
assembly. In my gas conversion(s) I have used the 36 mm long high volume pump
with the diesel pickup. The internal bore and the pressure relief side of the
valve are much smaller than the Golf/Jetta pan equivalents. I often pick
these up from junkyard engines, during my Sat. morning constitutionals. I
recently took one of the G/J pressure relief assemblies apart and found a
heavy deposit of caked or coked (overheated) oil which made the piston bind
at full travel.

Good post. This might be a place where new is good!
