Bill,

That's what I used to have and it lead to the failure of my
lift pump. That's why Yanmar sent me a letter threatening to void
my warranty it I used any filter smaller than 30 uM. That's
why the mechanic in FL said that they replace hundreds of failed
lift pumps a year due to folks using 2 uM Raycors. Mostly because
the engine mounted filters are harder to charge because they
generally require the system to be bled. So folks use a Raycor that
is too small out of laziness to avoid changing the engine filter. The
stress on the lift pump causes it to fail prematurely.

Engine is a Perkins 4-236. It burns 1 GPH. Don't know the true
flow rate but the return flow rate is pretty small.

The filter on the engine seems to prevent ,ost remaining gunk from
reaching
the injector pump and injectors. It must since it seems to be the one
that
was clogging up most.


Like I said, look into putting a large size small micron filter BEFORE the
engine mounted one. I want my filtration system to stop crud before it
gets to
the engine filter.
By the way, and I might have missed this, what kind of engine do you
have? And
what is it's true GHP flow rating? In other words it's burn plus return
GPH.
