Agreed, but a little cross-industry practice.... Typically, diesel
engines use a primary filter before the fuel pump, and a secondary after
the fuel pump. The idea is to protect the pump from trash from the tank,
and protect the injection system from chips and shavings, etc., from the
pump. I agree, one filter was originally fitted, but two may not be all
that extreme. Admittedly, a rubber diaphragm in the fuel pump is not
subject to the same abuse as diesel injectors, but someone may have been
applying some common sense and a little extra money. <g>
Cheers.
