Subject: Fuel transfer/polishing pump

The memo from Yanmar (via Mack Boring) didn't make any distinction
on type of filter. Just the porosity on the element. Perhaps it was a CYA
move to specify anything smaller than 30 uM.


If that's the case, then you have to do what they say.
At least until the warranty runs out. :-)
