and they are all blaming the ULSD diesel. They all have the same one-page
notice displayed. Says that conditioners such as Stanadyne can replace the
lubricity lost in the refiining, but that the aromatic chains (whatever the
heck those are!) are altered, no conditioner can fix this, and pumps may
leak as a result. 


One quart 2-stroke to a tank full should do it

Last July, I was on a 1000 mile road trip and ran in to ULSD in NW Ontario.
On the way home, around Sudbury, i srang leaks at ne of the line couplings
where it fastens to the check valve on the pump, and around the timing plug

Slacked each off, and retightened (using backup wrenches) and no more problems.
No gasket / Oring problems yet. A 94-A3, 1.9.
